For more than four months, DJnotaDJ has straddled the bandnotaband boundary. The Lawrence-based livetronica quartet hasn't surfaced for shows or studio time since a smokin' Snoop Dogg tribute last Halloween. Fortunately for fans of futuristic funk, DJnotaDJ has emerged from its hibernation well-rested and ready to resume simulating techno with guitar, bass, keyboard, sampler, drum set and flute. Unlike industrial music, which re-creates bleak factory-floor settings, the band generates electronically enhanced grooves, sounds that might emerge from a robotic rave. DJnotaDJ echoes techno's throbbing pulse without succumbing to its punishingly repetitive percussive schemes. Instead, it improvises like a jam band, guiding its robust drum-'n'-bass rhythms down unpredictable paths. Thursday's gig, featuring turntablist and frequent collaborator Nezbeat from opening act Archetype, emphasizes the group's hip-hop side.
