Just in case you didn't already know, this SMMR's raddest festival is about to knock its nuts upon our fair city at Plan B tomorrow. SMMR BMMR has been raging hard since 2008 and this year looks like the nastiest lineup yet. Seriously though, this isn't the "wax up your board" or "buy a Volvo" kind of summer music pap. This is honest to god head-exploding music to crash your dad's car to.
