The Flaming Lips have spent a lot of time recently collaborating with different artists. They released an EP with Yoko Ono and the Plastic Ono Band, announced plans to record with Bon Iver, and released a track with Erykah Badu (plus Siri), in addition to several others like Neon Indian and Prefuse 73.

The band has announced official details for the album, which is called “The Flaming Lips and Heady Fwends.” It will be available on Record Store Day — April 21 — on two discs of multicolored 12-inch vinyl. Because of the splattery nature of the vinyl, no two will look alike. This will apparently be the only pressing of this album, which features artists running the gamut from Nick Cave to Ke$ha.

Check out the track list below. The Lips are also releasing a Side by Side Series 7-inch with Mastodon, where both bands perform the “Soft Bulletin” song “Spoonful Weighs a Ton.”
