Led by drummer Damon Che, the mostly instrumental Pittsburgh band Don Caballero got its start in 1991 playing an especially knotty, roiling, metallic brand of post-rock. For all the anarchic, experimental turbulence in the group's tunes, the madness came with a method: Che is a first-class arranger and player with a clear vision. That may be why he's been branded "difficult," or why Don Cab has endured long hiatuses and wholesale lineup changes (he is the only remaining original member). Last fall's Punkgasm was complex and dynamic, the most straightforward album the band has offered to date.
