I caught some of Typical White Male's set. Good stuff. Then Sharpwaist. Also good stuff. Mavis Concave was cool but not especially my thing. And then Hrvatski, the reason I went to BS in the first place.
Hrvatski is Keith Fullerton Whitman. It's the name he used when playing his glitch/breakcore shit. He doesn't really do that too much anymore. Mostly droney/noisey stuff now. But he was/is the fucking MASTER glitch man. To see him play as Hrvatski live was like a fucking dream come true. Very rare, very exciting. Totally mind blowing. Best electronic set I've seen all year.
