Karen O is releasing a solo album this September.
The Yeah Yeah Yeahs frontwoman has announced that her debut record, 'Crush Songs', will drop this autumn via The Strokes singer Julian Casablancas' Cult Records.
The music was written between 2006 and 2007 and is described as a "collection of lo-fi, bedroom recordings".
Karen explained: "When I was 27 I crushed a lot. I wasn't sure I'd ever fall in love again. These songs were written and recorded in private around this time.
"They are the soundtrack to what was an ever continuing love crusade. I hope they keep you company on yours."
A limited vinyl edition of the album will be available pre-release with artwork featuring Karen's own drawings and handwritten lyrics.
Julian commented: "So excited, lucky and proud to be involved with such a classic album - I just wanna listen to it all day. Karen is an all-time great."
The Yeah Yeah Yeahs' last album, 'Mosquito', was released in 2013 and the indie rockers have not yet announced plans for new music.

Lily Allen has split from her manager.
The singer has parted ways with her long-time aide Todd Interland, who has looked after her music career since her debut in 2006.
This comes after Lily slammed her record label for making her release "rubbish" light-hearted pop songs like 'Air Balloon' from her comeback album 'Sheezus' over less commercially-viable tracks like 'Hard Out Here'.
A source told The Sun newspaper: "Lily guides her career herself a lot but will need someone new to work with her. Todd had been with her for a long time so it was a blow to lose him.
"She's looking around at the moment for the right person to help her make the correct decisions with her music."
Before finding a new manager, Lily, 29, is heading to Glastonbury festival this weekend, where she will take to the stage before Arcade Fire.
The mother-of-two - who temporarily quit the music industry in 2009 to raise her daughters Ethel, two, and Marnie, 16 months, with her husband Sam Cooper - recently said she felt frustrated by her lack of control over her music career.
She sighed: "I'd like to [release the songs I want], but unfortunately I signed a record deal! I took a mortgage out on myself, that's how it works."

Niall Horan has begged fans to stop throwing objects on stage.
The One Direction heartthrob injured his knee during a gig for their 'Where We Are Tour' in Amsterdam, Holland last night (25.06.14) and took to Twitter after the show to ask the band's over-zealous fans to stop hurling heavy items around during their concerts.
He posted: "Amsterdam thank you for a great couple of shows! Appreciate you coming.
"Also guys! Can you limit what gets thrown on stage please! Coz somethin thrown at me tonight! Hit my knee! A lot of pain from it!
"Never wana sound like I'm complaining! But only having my operation 5 months ago, I still get a bit of pain and I'm very scared about it. (sic)"
Niall - who had major knee surgery in January - was seen limping around the stage in a video of the concert obtained by the Daily Mirror newspaper.
One devastated fan raged: "HE CANT BARELY WALK ITS SO SAD. (sic)"
The Irish singer's bandmates didn't escape unharmed either since poor Harry Styles was hit in the face by an unidentified flying object last night.
The 'Kiss You' hitmaker looked less than impressed when an item was chucked at his head, poking him in the eye, but barely missed a beat as he bounded around alongside Niall, Louis Tomlinson, Liam Payne and Zayn Malik.

Emily Ratajkowski claims she's a "weird" version of herself in the 'Entourage' movie.
The brunette beauty - who was catapulted to fame in the music video for the controversial 2013 hit single 'Blurred Lines' by Robin Thicke, Pharrell and T.I - was cast in the big-screen remake of the HBO series and claims that although she plays herself, the character is nothing like her.
She explained to GQ magazine: "That show's always been so funny to me. I'm playing myself, and they've got me in an Aston Martin. I drive a Nissan Versa and would never spend real money on a car, because I destroy things.
"So there's this weird version of yourself. Hollywood fetishizing you and itself - this box within a box.
"There is winter in Los Angeles, there is rain in LA. But there is no rain on 'Entourage'."
The 23-year-old star is also set to star alongside Ben Affleck in 'Gone Girl' later this year and director David Fincher previously revealed they felt she was the perfect choice for her character.
He said: "She was just incredibly mature. She wasn't smitten with being the girl of the moment. She's no bulls**t. If somebody's going to ruin their life on a 21-year-old, they have to be special, and she was."
'Entourage' is scheduled for release in June 1015.

Glastonbury organisers are adamant Prince "isn't coming" to this year's festival.
The 'Raspberry Beret' hitmaker, who was in talks to headline the event but pulled out because of "social media rumours" that he would be playing, will not make an appearance at Worthy Farm, according to Emily Eavis.
She claims the Friday 11am slot on The Other Stage hasn't been announced yet but fans will be disappointed to learn Prince will not be filling the spot.
Emily told NME magazine: "I don't know who it is. There may well be some secret sets elsewhere, but Prince isn't coming.
"We always have conversations with Prince, every year. Maybe one day it will happen. For The Rolling Stones last year, we'd talked about doing it 10 years before. It's a timing thing for everyone."
Emily, whose father Michael Eavis started the festival, claims there is a right time for someone to do it and it's not the right time for Prince.
She added: "I think a lot of people want to see him here, and probably the more people ask him, the more he thinks no. But I don't know!"
Michael claims they wanted him to play but before he confirmed he got "really upset" because he thought the festival had advertised that he was playing.
Michael said: "We hadn't, but with social media, rumours get everywhere, and one of those rumours was that Prince was coming. So he didn't want to do it in the end."

Ozzy Osbourne felt like a "f***ing laboratory rat" on his family reality show.
The Black Sabbath frontman insists he doesn't regret taking part in 'The Osbournes' with wife Sharon and children Jack and Kelly, but is equally relieved the fly-on-the-wall show - which ran from 2002 to 2005 - came to an end when it did.
He said: "It was an experiment. Looking back, I'm glad we did it but I'm glad we jumped off when we did after three years of feeling like a f***ing laboratory rat.
"We went from being a relatively normal family to this f***ing family that was blown apart. It has taken a long time to get back together. The only good thing about it is that Sharon got a career out of it."
Ozzy insists it wasn't his decision to make more than one series of the show and he only went along with it to keep his family happy.
He said: "Sharon would say, 'Do you want to do another season?' and I'd go along with it because they're family. At the end of it, I was f***ing wiped out, my whole family was disintegrating.
"My wife was in bed for nine months battling colon cancer, my kids were all in rehab, I was f***ing dying. I just wanted to get my rock 'n' roll life back."
And the 65-year-old rocker admits he has never even seen an episode of the programme.
He told Time Out magazine: "I never watched an episode of 'The Osbournes', I don't like to see myself on TV. That's why when Sharon says so-and-so want to do a pilot for another TV show, I say, 'Sharon I'm a rock 'n' roller. I didn't join a band in 1968 to be a f***ing weather reporter on the f***ing six o'clock news. I don't want to know. Leave me out of it."

Lorde thinks Taylor Swift is an "incredible role model".
The 17-year-old star has praised her singer pal for setting a good example for young girls through her music and thinks they are close because they both understand the music business.
She explained: "I think there are artists who are really incredible role models and that's something I admire. I feel like Taylor is a really good role model and I think that the girls who listen to her music are so devoted to her, and I think what she's saying is pretty cool. It's empowering.
"If we have the same work problems, we know each other's lives better. It's always good befriending people who do a similar thing."
Before they became friends, the 'Royals' hitmaker criticised Taylor, 24, for being "perfect and unattainable" but Lorde says Taylor wasn't offended by her comment.
She revealed: "She was like, 'It's fine, if all you've done is call someone perfect it's not a bad thing.' "
Lorde also hit out at Taylor's best friend Selena Gomez, 21, over her sexually suggestive song 'Come and Get It', and the New Zealand-born star admits she has learned her lesson from the media storm her remarks created.
She said: "I feel weird talking about it because I stated an opinion and people took that and made it mean something. It's easier never to talk about anyone else's work because they might take it the wrong way."
While Lorde looks up to Taylor as a role model, she is reluctant to be considered one herself and hopes her fans realise she's not perfect.
The singer elaborated: "I'm probably going to screw up at some point - probably soon - and people are going to say, 'You're not a good role model.' But I figure, I'm 17 and I'm very much perfect. I'm figuring this out too and I think people are aware of that."

Tori Spelling and Dean McDermott "are moving in the right direction."
The couple, who documented their battle to save their seven-year-old marriage on their latest reality TV series, 'True Tori,' after Dean checked into rehab following a one-night stand with Emily Goodhand in Toronto, Canada in December, are still working on their relationship, but are much happier.
The 41-year-old actress told 'Good Morning America' on Wednesday (25.06.14): "Things are getting better. You know, life is always a work in progress and our relationship is one as well, but we are moving in the right direction."
The 'Mystery Girls' star has no regrets about airing their personal problems on TV, even though they have four children, Liam, seven, Stella, five, Hattie, two, and Finn, 22 months.
She said: "Some people approved of it, some people didn't. It was my personal journey and I have no regrets."
The former 'Beverly Hills 90210' star later echoed her comments on 'The View,' saying: "I feel like all relationships are a work in progress and we're working on it right now. We're trying."
A source previously revealed that Tori was eager to save her marriage for the sake of her children.
In April, the insider said: "Tori doesn't want her kids to grow up without their dad in the house."

Justin Bieber is being sued for allegedly crashing into a pedestrian last year.
The 20-year-old singer, who was cleared of hit-and-run charges in connection with the same incident last summer, has been named in a new lawsuit by photographer Walter Lee, who claims he suffered severe injuries after being struck by the 'Baby' hitmaker's white Ferrari on the Sunset Strip in Los Angeles last June.
According to court documents, obtained by gossip website TMZ.com, the plaintiff is seeking damages to cover his medical bills and says he may never fully recover from the injuries, including lacerations, haematomas, deep abrasions on his left leg and deep venous thrombosis.
Police officers investigated the incident last July after the photographer claimed he was caught between Justin's Ferrari and a parked vehicle, as he took pictures of the singer leaving the Laugh Factory in West Hollywood, and accused Justin of driving away from the scene.
The Canadian star was questioned, but released without charge and a law enforcement source previously said: "Prosecutors say there was insufficient evidence to prove that [Justin] knowingly left the scene of a collision in which someone was injured."
News of the civil case comes just days after Justin, who recently rekindled his relationship with Selena Gomez, was involved in a minor collision in Beverly Hills on Tuesday (24.06.14).
The singer was travelling in an Escalade when it was hit by a BMW that was pulling out of a parking garage, but no one was injured.
An eyewitness said that the 'Confident' hitmaker - who wasn't behind the wheel - was unfazed and almost immediately jumped out of the SVU and into another vehicle to continue his journey.

Kesha is still learning to accept her "beautiful imperfections."
The 'Timber' hitmaker - who sought treatment in a rehab facility near Chicago for an eating disorder earlier this year - says admitting she had a problem is "the scariest thing" she's ever done, but she no longer cares what anyone else thinks about her.
The 27-year-old star told Teen Vogue magazine: "My eating disorder is something I've been struggling with for a while. People will make up stories, but I went to rehab for an eating disorder--nothing more and nothing less. I decided to face my problem head-on."
She added: "My whole message is to love who you are and accept all your beautiful imperfections. When I felt I was slipping into unloving territory with myself, I knew I had to listen to my own advice and correct it...I felt I needed to get help, not only for myself but also for my fans. My worst fear in life is to be fake."
The 'Tik Tok' hitmaker also believes being in the spotlight intensified her insecurities and made her feel more self-conscious about her weight.
She said: "It really messed with my head, and I realised I couldn't do it by myself. The decision to take control of it is the scariest thing I've ever done, and this is coming from someone who dives with sharks and jumps out of airplanes for fun."
The singer, who spent two months in rehab, wrote 14 songs while she was there and feels back in control again.
She said: "The whole process has made me so much stronger and ready to take my life by the horns and make a record that I'm going to be proud of and not care what anybody else thinks!"

Jessica Simpson will reportedly walk down the aisle in a pale pink wedding dress.
The 33-year-old star is set to marry fiancé Eric Johnson in Santa Barbara, California early next month and has decided to wear a custom-made Marchesa gown with a modern twist.
A source told In Touch magazine that it took Jessica more than a year to decide on the dress.
A spokesperson for the designer hinted the speculation is true, but told E! News: "We are unable to comment on this matter at this time."
Earlier this year, Jessica said: "I already know the silhouette that I want."
Meanwhile, the couple, who have a two-year-old daughter, Maxwell, and a 12-month-old son, Ace, together are planning to treat their guests to a huge barbecue spread at their lavish reception.
A source previously revealed that Jessica, who was previously married to Nick Lachey, and Eric have booked the 78-acre Bacara Resort & Spa in the beach-side town for their nuptials, but the blonde beauty is still undecided as to whether she actually wants to get married there.
An insider recently said: "They've booked it for now. But Jess keeps going back and forth on locales."
The bride's sister Ashlee Simpson has said she is thrilled with the bridesmaid dress she will wear on the big day.
She said: "My dress is really beautiful! It's really, really stunning."

Behati Prinsloo celebrated her bachelorette party in Miami.
The Victoria's Secret model was joined by a huge group of female friends, including South African supermodel Candice Swanepoel, at the Wall nightclub at the W Hotel in South Beach ahead of her upcoming nuptials to Adam Levine.
A source told E! News that the girls "danced, drank and partied" the night away.
The 25-year-old beauty also shared several pictures from the bash on Instagram earlier this month, before she flew to the Bahamas to relax before her wedding.
Behati, who hails from Namibia, is set to marry the Maroon 5 frontman, 35, in Mexico this summer.
The 'Misery' hitmaker toasted their nuptials at his bachelor party in Last Vegas with his friends last month.
A source said: "Adam and his group of 55 (all gentlemen) dined in the private dining room of N9NE Steakhouse.
"The entire restaurant recognised Adam right away, and he stopped to chat with several guests."
An eyewitness added that Adam "was all smiles and appeared to be in great spirits."
The couple first started dating in May 2012, but briefly split last year.
The 'One More Night' hitmaker enjoyed a brief romance with 22-year-old model Nina Agdal in May last year during his time apart from Behati, but they soon reunited and announced their engagement.
A source said at the time: "He realised he really does love her and she was the one."
