THURSDAY SEPTEMBER 29

CARL COX, EVIL NINEAlmost unanimously loved worldwide for his three-deck DJ sets, Cox maintains a fine balance between accessibility and cutting-edge material. His bread-and-butter elements remain, pumping psychedelic, mesmerizing, and sensual techno and house. Cox is also revered for his ability to appeal to diverse crowds, and to build incomparable energy levels in dancers. Anyone whose sets encompass Green Velvet, Adam Beyer, and Jeff Mills is aces in my book. Opening are UK duo Evil Nine, who released You Can Be Special Too earlier this year, a clunkily funky and bludgeoning amalgam of breakbeat styles with rapping cameos by Aesop Rock, Juice Aleem, and Toastie Taylor. With Dig-Dug. Showbox, 1426 First Ave, 628-3151, 9 pm–2 am, $20 adv, $25 DOS, 18+.

FOUR TETEnglish laptop wiz Four Tet (Kieran Hebden) found himself the unwilling poster boy of folktronica after dishing out the innovative full-lengths Pause and Rounds. But with 2005's Everything Ecstatic, he leaves behind the idyllic digital gamboling and forges a new species of rhythmic legerdemain that lives up to its brash title. Ecstatic is Four Tet's most Kraut-rock-inflected and psychedelic work to date—and his funkiest. With Koushik. Neumo's, 925 E Pike St, 709-9467, 8 pm–2 am, $13 adv, 21+.

SATURDAY OCTOBER 1

GLENN UNDERGROUNDUnbelievably, veteran Chicago house-music icon Glenn Underground makes his Seattle debut tonight. A producer with releases on revered labels like Guidance, Cajual, Masters at Work, and Peacefrog, Underground (AKA Glenn Crocker) gets props for updating and deepening the classic Windy City house sound for heads who can also handle free jazz and classic disco in their bumpity-bump clubbing experience. This should be historic. With Tom Mitchell. Baltic Room, 1207 E Pine St, 625-4444, 9 pm–2 am, free before 10, $8 after, 21+.

KJ SAWKAKJ Sawka celebrate the release of their strong new album, Synchronized Decompression, a dynamic fusion of drum 'n' bass dynamics (featuring the gobsmackingly dexterous drumming of Kevin Sawka) and soulful songwriting. With Electrosect, m.O., Christa Wells, B-Shorty. Chop Suey, 1325 E Madison St, 324-8000, 9 pm–2 am, $7, 21+.
