MAD PROFESSOR AND DJ VADIM

Wonderfully deep dub madness (that's dub, minus the step, but plus the wobble) from the legendary Mad Professor should set it off for heads into quality nods. Trip-hop — yes, I said trip-hop, no shame! — trailblazer DJ Vadim comes from Russia with a sonic palette to rival some hypothetical Timbaland Monet. Dip the brush and swirl.

TEKANDHAUS

Fresh local, um, tech and house upstarts Bells and Whistles (of the excellent DRESSCODE parties), Nightlight Music's Travis Dalton, and Zenith bring some twilight hustle to Anu. This should be the kind of low and bristly affair, flavored with a moody dusting of machine soul, that leads you onto other avenues.

Fri/16, 10 p.m., free. Anu, 43 Sixth St., SF. www.anu-bar.com
