This surely looks like a fun bill: In the headline slot, coed duo Math the Band soups up its rowdy emo-punk with a caffeinated electropop engine—imagine a goofier, more unhinged Matt and Kim. Warming up the stage you have punk-steeped marching band the What Cheer? Brigade, plus Cherie Lily—personal trainer to the stars, wife of Andrew W.K. and creator of Houserobics. And in the opening slot, local longhair belter Corn Mo leads .357 Lover through gloriously hammy rock-opera goodness.
