there is a show listed at the leland club from 10:00-4:30 with this band playing, and they insist there will be music until 4:30.
i've been, err, phished a few times by that club. and, i wish this was a little bit more abstract than it is.
that said, i'm sure they'll go until at least 2:30, so if you're a little less hardcore than i am, it's no doubt long enough. and, if it was just a bit more abstract...
that said, i haven't completely ruled it out yet, either.
