Billboard is reporting that the follow-up to 2006′s At War with the Mystics will be a double album, and is scheduled for a late Summer release. And according to a previous Stereogum progress report, the album may be entitled Embryonic.

Front-man Wayne Coyne told Billboard that 13 tracks have been written so far, with eight or nine more expected.

“I think with this there was an element of accidentally stumbling upon more spontaneous sort of freak-out stuff,” Coyne says. “We were sitting at (drummer) Steven’s house and we just started out having these freak-out jam sessions where he’d play drums and I’d play bass and we just would sort of do freaky stuff. Some of those recordings, even though they’re not recorded very well, really had a spontaneity about them that we probably wouldn’t have purposely done.

“So we just went with some of that and use those as sort of the bedrock of what we’d do later on with overdubs and lyrics and stuff like that. It sounds very exciting.”

In other Flaming Lips news, the band will be headlining the Pitchfork Musical Festival. Additionally, the band will be making an appearance on the upcoming Danger Mouse/Sparklehorse/David Lynch collaboration entitled Dark Night of the Soul. We’d like to note that the previous Dark Night of the Soul tracklist that was posted was incorrect. It has now been corrected.
