The interesting thing about Bassnectar — one of the qualities that makes S.F.-based longhair Lorin Ashton stand out from the pack of electronic dance music producers making guts rumble across the world — is his interest in variety. Sure, Ashton lives up to his stage name with plenty of stomach-churning low-end, and he manages to make post-dubstep wub-wub-wub more tasteful than most big names. But Ashton also throws in elements of other electronic genres like drum 'n' bass into his productions, and even flirts with hip-hop beats and shards of heavy metal. That's not totally surprising: Before he became obsessed with rave culture, Ashton was a denizen of the Bay Area's metal underground scene. After years of toiling in obscurity, he's now riding high atop the wave of EDM popularity. Don't miss a chance to see the man make his home city shake.
