IT'S SO BASSY AND FUTURISTIC: HXDB AND ILL COSBY

Catching a DJ set by local future-bass-music facilitator Ill Cosby is one of the most effective ways of keeping tabs on developments in innovative electronic music. If for some lame reason you can't make it to Electric Tea Garden tonight, check out his webcasts at Sub.FM and follow his Car Crash Set label's power moves at www.carcrashset.com. I humbly submit that this will be the best advice I'll dispense in Data Breaker all week. Mr. Cosby brings in from Vancouver one HxdB, a producer/DJ with releases on Palms Out Sound, Tectonic, Car Crash Set, and other fine purveyors of high-level, head-nod-inducing beats. Hexadecibel's music is marked by a nocturnal sensuality and poised, articulated rhythms that rarely do the expected thing. With Eugene Fauntleroy and Sho Nuph. Electric Tea Garden, 9 pm, $5, 21+.

SUPERSTAR DJS TODD TERJE AND TIM SWEENEY GET INTO TROUBLE

Whoa, this looks like the best bill that the disco connoisseurs behind Trouble have booked yet (with an assist from the Slowpøke crew). New York–based Tim Sweeney has earned scads of good sonic karma through his Beats in Space webcasts, in which he takes you on a proverbial journey that leaves you disoriented yet euphoric. His sets are smartly eclectic, often zagging when you think they're going to zig, and vice versa. Norway's Todd Terje is another DJ/producer with excellent, wide-ranging taste. He's also made some killer reedits, such as those of Chic's "I Want Your Love," Kraftwerk's "Home Computer," and Stevie Wonder's "Superstition." Terje once told Resident Advisor, "I like my music very fruity. Lots of percussion, lots of silly effects. But I still need that dubbiness and spaciousness. It's a strange combination." If that doesn't sound intriguing to you, you're reading the wrong column. Fred Wildlife Refuge, 10 pm, $12 adv/$15 DOS, 21+.
