Following their big performance this past weekend at Lollapalooza, Alt-J can also celebrate their own concert film, which will be released next month in theaters nationwide.

Artists Den Presents alt-J, which chronicles the British trio's intimate performance at Hollywood American Legion in Los Angeles, can be seen in 400 U.S. theaters starting on Sept. 2, ahead of the extended Labor Day weekend.

The 90-minute film will feature an exclusive interview with the band and performance footage from the Los Angeles show, with only 600 guests allowed.
