Housing both the Unabomber (suspect—yeah, right) and the Next American Revolution, Montana’s in the news these days as a crackpot magnet. Another angry fellow with roots in Montana—Steve Albini—lends his signature sound to fellow Big Skyers Silkworm’s new chunky and angular double LP, Firewater. It is a match made in, uh…well, Chicago. Andy Cohen’s aggressive guitar lines balance Tim Midgett’s Cimmerian outlook, and we reap the rewards. Dischord’s Smart Went Crazy and Milwaukee heavy-hitters Dis open at 9:30 p.m. at the Black Cat, 1831 14th St. NW. $6. (202) 667-7960. (John Dugan)
