Huh, they didn't have crowd visual foldback? How could they tell they weren't playing to an empty club?
Perhaps they're shy.
Off topic, but be careful about letting Treephort and their flaming thongs on your stage.
They played an incredibly small bar in Pittsburgh in late 2002. Good show- cool guys, very multimedia, very political/bondage presentation. Personally, I like the full live effect quite a bit more than just the music alone- this sort of presentation/aesthetic would do well on a Skinny Puppy tour, I think.
Nice to see they've made the West coast!
