Taking some time off from touring, Vampire Weekend has headed back into the studio to record their sophomore LP. The band has been recording in Brooklyn and are shooting for a release this upcoming September.

Vampire Weekend has finished up writing all the material for the new record, and told the premier music outlet Entertainment Weekly that Rostam Batmanglij, the band’s keyboardist, will be producing the studio sessions.

“For the last month or so, it’s just been us by ourselves in this small studio, working every day,” Vampire Weekend’s Ezra Koenig told Entertainment Weekly. “It’s nice after having been on tour so much to be in a slightly different situation, but it’s pretty intense. We’re really trying hard to do everything that we want to do.”

The band has already debuted one of the possible tracks for the new, yet-untitled album when they performed “White Sky” on Jimmy Fallon last month, and Koenig said they have recorded the song, but it will feature more synth sounds and be more pumped up than the acoustic version they played on the late night show. Vampire Weekend is also promising a hint of a new sound to come out of the upcoming record.

“It’s definitely going to be a recognizably Vampire Weekend sound, but there are going to be new sounds,” said Koenig. “We’re trying to challenge ourselves not to use the same bag of tricks that we used on the first album; different instruments, stuff like that.”
