San Francisco grups were in full effect Friday night, as the hot demographic of 30-something indie-yuppies swept into the Cafe Du Nord Noise Pop event of the evening. For the record, it was singer-songwriter night, with Jason Collett (from the Canadian Broken Social Scene crowd) headlining, but the crowd had that vaguely open-minded/not-as-plugged-in-as-they-once-were feel of "let's go check out some New Indie Rock on Friday night after work." (We totally put ourselves in that group! We read that article about the Broken Social Scene in the New York Times!)

When indie rock is no longer your life, and is instead your after-work hobby, you approach the whole concert thing differently. For instance, we saw folks IMing on corporate Blackberries and having loud conversations about office politics throughout the entirety of the Submarines' delicate set. No one was shouting out the names of obscure B-sides for any of the performers. It was actually kind of nice to have all that indier-than-thou pressure off, though we did feel bad for the Submarines.

Etienne de Rocher's set was notably enlivened by an old-fashioned really-into-it fan, who flung out her Solid Gold dance routine, all thrashing head and horse-kicking calves. It was especially cool because de Rocher's set was actually kind of medium-tempo and introspective, like Jeff Buckley. Highlight of the evening: at the climax of one of de Rocher's songs, this woman let out a triumphant shriek, and the entire audience involuntarily took a half-step back. She definitely brought an indulgent smile to the faces of the crowd. , you could see people thinking.

Collett's set of rainy Sunday afternoon songs closed out the evening at around 1:30 a.m., as folks on the 9-to-5 stifled back their yawns of fatigue from the end of the work week. It's hard committing to the indie rock lifestyle when you've got bills to pay!

I used to love indie rock that much!
