If there happens to be a band in town at 9:30 club that you like while you're in town, go see it. This venue is intimate in that there are no seats, only 2 levels of standing room, but the lights and sounds are amazing. It books well known bands which will give you an opportunity to see some big name acts up close, without paying for a front row seat. The name of the club is the time most shows start, and unless it's all-ages night you don't need to show up right when the doors open. Actually chances are, if you do, you'll be one of the first to arrive and will spend an hour or so standing around the bar before any of the acts come on stage.
