WEDNESDAY 5/4

NO NORTHWEST COMP RELEASE PARTY

Ill Cosby's Car Crash Set label has been issuing a torrent of bass-music heat for the past couple of years, establishing itself as a favorite of discerning DJs worldwide. Tonight it celebrates the release of the excellent No Northwest compilation with performances by 214, Cedaa, and Ill Cosby (the latter playing back-to-back with qp). 214 (aka Chris Roman) has become one of America's top electro producers, Bellingham's Cedaa is a young gun poised to blow up in 2011 with his hypermelodic post-dubstep cuts, and qp creates fidgety woofer-blasters straddling electro and juke in an unnervingly dark and sexy manner. I've blathered about Cosby many times before, but it's hard to hurl enough superlatives at his multipronged program for manifesting quality electronic music. The man's a local treasure. Baltic Room, 10 pm, $5, 21+.

HUMAN DRUM MACHINE KJ SAWKA

Seattle drummer KJ Sawka is one of the few sticksmen who can lay down beats swift and intricate enough for live drum 'n' bass groups, which is what he does for Australia's Pendulum. His own material takes the genre to some menacing, gritty places with great dexterity. With Splatinum, Partners in Grime, DJ Keano. Neumos, 8 pm, $12, all ages.

WITCH-HOUSE DUO CRYPTS

You're likely going to the Croc for Zola Jesus, but you should try to check locals Crypts, too. I mean, how many opportunities do you get to catch an actual witch-house act in the flesh? Too few, Clyde. These guys will set a gauzy, indigo, agitated mood to complement that of Ms. Jesus. With Naked on the Vague. Crocodile, 8 pm, $10, 21+.

FRIDAY 5/6

DUG DIGS UP FRANK GOSSNER'S VOODOO FUNK

If you care about funk, you need to be here tonight. DUG's monthly funk/soul dance party already delivers connoisseur-level thrills via its residents' deep crates, but this month German DJ Frank Gossner blesses the decks with his even rarer platters that he scores from his epic searches in West Africa. Get up to speed with Gossner at www.voodoofunk.com. With Christian Science, Jon François Stone, Greasy, David James. Lo-Fi Performance Gallery, 9 pm, $7, 21+.
