Techno and house musicians are not exactly known for their riveting live performances. There are a few exceptions, however: Orbital, Lionrock, the Aloof, and Underworld. When Karl Hyde and Rick Smith teamed up with DJ Darren Emerson, Underworld evolved from a mediocre rock band to a great acid-house band. Underworld didn’t leave rock completely behind, though; it retained rock’s drive, attitude, and guitars. “Born Slippy,” popularized on the Trainspotting soundtrack, is one of the too few dance tunes loved by rock fans. Underworld’s new album, Beaucoup Fish, is a glorious return to the partnership’s house and Eurodisco roots: “Shudder/King of Snake” is a clear homage to the Giorgio Moroder-Donna Summer classic “I Feel Love.” Underworld performs at 8:45 p.m. at the 9:30 Club, 815 V St. NW. $25.
