The week starts on Wednesday at the Last Supper Club, where you’re as likely to see a Playboy model (somebody’s idea of a marketing scheme) shaking her groove thang on a riser as an honest-to-God real woman. Wednesday night Party Rock is sponsored by hard-rock station KISW-FM (99.9), but the following night’s long-running Open House carries on in the true fashion of those who celebrate casual Friday—being casually hungover. The only free night of the week, Open House features resident DJs Flave, Hyperfunk, and Jordan, whose efforts to keep things fresh and fun are rewarded by a packed house whether there’s a headliner or not. It’s something of a college scene, but not too much of a meat market—no parking on the dance floor here. Progressive House Saturdays have brought DJs from the populist BT to the esoteric Marco Bailey, and DJ Scene regularly holds it down in an underground chamber with arguably the best hip-hop selections in town.
