A few bands played. The first band I saw (who, I think, were called Davina Icon) looked like discopunk fashion models and played garage-rock with synths coming from somewhere off stage (possibly a MiniDisc, though the spiky-haired androgynous bass player may have been playing through a box that added synthy effects or something). The lead singer looked like an emaciated Sid Vicious, and was seemingly too thin for his pants; towards the end of the set, they started riding down, revealing a bit too much to the audience. After the end of the set (and presumably after pulling his pants up), he left the stage and immediately started posing for one of various photographers in the venue.
The second band was a boy-girl duo from LA named Mynx, who danced and sang over a backing track; they did a sort of electro cabaret, somewhere between the Dresden Dolls and Service Station Youth, with perhaps a bit of the Town Bikes thrown in. One of their songs had the chorus "I'm so LA".
The final band was named Luxembourg and was somewhere between indie and synthpop, sounding in places like Pulp or (as Lloyd from Schmoof, who was there, pointed out) The Cure's bouncier moments. They were entertaining enough.
