A bad DJ, like a recently retired athlete, fills fans with sadness and owns multiple records that are bound to be broken. Let upright professionals do the spinning with today’s GrouponLive deal: for $12, you get one general-admission ticket to see Moby at the Showbox SoDo on Friday, September 30, at 9 p.m. The performance is part of the Decibel Festival.

Moby, the preeminent one-man force of multifaceted dance music, brings his intuitive beats and DJ skills to the the Decibel Festival, Seattle’s celebration of media, electronic-music performance, and visual art. For decades, Moby has fused genres with a turntable blowtorch and ridden the faders like a manic master of marionettes, resulting in more than 20 million in record sales and impenetrable credibility. From his disco Lamaze birth to punk adolescence and laser-caressing career, Moby has architected house music and techno, perplexed audiences with his capricious grab bag of styles, and saved critters from motorcycle-gang gallows with his passion for philanthropy. On the heels of his combination album and book, Destroyed, Moby’s live DJ set jostles audiences in a series of virtuosic rhythm quakes. Shaking the rest of the stage, fellow New York dance dilettante Alexi Delano twirls platters of atmospheric techno, and Brooklyn-based duo Blondes churns keyboard butter into astronaut food for the ears.
