MGMT have a name for their second album -- 'Congratulations.'

The electro-pop duo are promising a darker blend with their new album, which will come out some time next year, two years after debut 'Oracular Spectacular' made them indie darlings.

Singer Andrew Wyndgarden (pictured) told the San Francisco Examiner the album's title track is "pretty dark."

"It's us trying to deal with all the craziness that's been going on since our last album took off. Sometimes it just doesn't feel natural," he said.

The new album has one track featuring vocals from Royal Trux's Jennifer Herrema.

Last week the band played San Francisco's Treasure Island festival, and also played a last-minute secret gig at the city's Independent.

The band have already played three of the songs expected to be on 'Congratulations' during their summer appearances.
