There are usually two kinds of band reunions: the kind in which a band plays the hits from its heyday, and the kind in which a band attempts to pick up where it left off, writing new material. Seminal Bostonian post-punk act Mission of Burma is doing a bit of both. Formed in 1979, the band released only one full length, Vs., before calling it quits as a result of guitarist Roger Miller’s tinnitus. In 2002, the band reunited and has since toured regularly and recorded more full-length albums than in its original incarnation. On Burma’s current tour, titled “Definitive Editions,” the band members are breaking from their usual blend of old and new to please their more nostalgia-hungry fans. They’ll play Vs. in its entirety throughout the tour, showing that, while they’re not living in the past, they’re not afraid to look back. Mission of Burma performs with Versus at 9 p.m. at the Black Cat, 1811 14th St. NW. $15. (202) 667-7960.
