I went to Midwest Mayhem last weekend, which is KDHX's (the local independent radio station) annual bash at the City Museum (which is really more of a playground made out of found objects). The Museum is such a perfect place to host this eclectic, indie event, and it was packed. (I heard there were something like 2,000 people there, but spread across 4 stages.)
My favorites of the evening: Rum Drum Ramblers, The Grass Pack, The Dock Ellis Band, and the Funky Butt Brass Band.
Sara Finke took a *ton* of great pictures.
