The Flaming Lips have announced that they will release their eagerly-awaited new album, 'At War with the Mystics', on 4 April.

Billboard reports that the first single, 'Yeah Yeah Yeah Song', will be released on 27 March.

A final tracklisting for the album, the follow-up to 2002's 'Yoshimi Battles the Pink Robots', has yet to be announced.

Among the songs expected to feature on the album are 'Space Bible', 'Time Travel' and 'The WAND'.

Commenting on the album, frontman Wayne Coyne said: "There are some tracks we've delved into production-wise, where we're trying to get some of that heavy rock 'n' roll with heavy guitar riffs, but not just to be aggressive. On the last couple of records, we've tried to be more expressive in beautiful ways. But sometimes, volume and intensity are great too."
