If you see nothing else at UCB, see Death By Roo Roo on Friday night. For that matter, see anything with Jackie Clarke in it. The Stepfathers are also worth seeing on Friday, and Reuben Williams on Saturday, and it looks like Bro'in Out on Monday the 20th is going to feature the impossibly lovely John Oliver (and Andrew WK?!). I haven't been to a proper non-marathon ASSSSCAT in ages so I can't really speak for it -- anyone know who's in it these days?
Also, CMJ is in October...did you mean you were coming then? If so, pls disregard everything I just said.
