Fucking do it. They're awesome live. There's all this power and shear madness live, and it makes the records look really, really tame (and sound really really weak) in comparison. I saw them last August for $6 in a tiny shithole bar, and it was one of the most fun shows I'd ever seen. They just tore through their 40 minute set, without stopping. Satomi does little interpretive dances to the songs while she plays, too, which is pretty hot. When we begged them for an encore, they got up on stage and played the first song again.
Don't miss them. I mean, even if you're hit or miss on their records, they're one of those bands that's like ten times better live. Seriously.
White Man can probably back me up on my claims.
