If you think "Deep Chicago House" means pizza, you'd better scoot on down to Enigma and Club Purple on Saturday, December 14, when Terry Mullan performs two sets to double your pleasure. A harbinger of Chi-Town's next generation and a veteran of old-school warehouse rhythms, Mullan masters the mixes without breaking a sweat. His Catalyst label has spawned clubland hits and paired him with hipsters such as H-Foundation's Halo. Mullan's touring has decelerated lately to leave more time for work in the studio, where his extensive background as a performing musician contributes to his quirky but compelling compositions. The DJ attributes his success to an innate ability to guide "the crowd on a spiritual journey" with each show. Be sure to pack your bags before heading to either -- or both -- of his twin shows.
