Comet talent booker and DJ Mamma Casserole (aka Michelle Smith) has earned the love of many in Seattle's music scene for her excellent musical taste, generous spirit, and infectious gregariousness. Tonight, several of the Northwest's most interesting garage- and psychedelic-rock bands converge on her home turf to celebrate this musical dynamo's born day. Purple Rhinestone Eagle, the Curious Mystery, Nudity, Tiny Light, and the Night Beats light the birthday-cake candles and—figuratively, of course—set the night on fire.
