do take in to consideration that APTBS has probably gained a little more attention/following since they were last here, so that might fill up the place a bit more.
get there early if you're not going to buy in advance. maybe swing by the club, buy tix, then go out for food/drink?
APTBS + RnR hotel = you can't bring earplugs that are strong enough. the band plays LOUD and the venue is happy to crank it up. ears will bleed. also, the room is long and narrow, and the stage is low = crappy sightlines if you're not towards the front. not a problem if the show isn't sold out, definite issue if it is.
400? Ugh thank God I've never been to a sold out show there.
won't you be seeing phoenix there?
