Great local bands, free crawfish (for the first two hours) and the Hawaiian Tropic girls in bikinis. Ah, spring is a good time to be alive in Houston. This first of a (possibly) yearly series of Rock 'n Boils is an attempt to marry music with mudbugs. The lineup (in order) is Ashbury Keys, Moriah, Shawn Pander, Moses Guest, Gel and Overshot, all of whom will play sampler-friendly one-hour sets. Organizers promise that "A&R label/ talent scouts" will be in the audience (hmmm, could they be the middle-aged men with ponytails?) and are encouraging even bands not on the bill to drop off demos at the door. 18 and up.
