Milwaukee's Hugh Bob and the Hustle have been roaming America's highways and rock clubs for nearly three years. Their 15-passenger Chevy van is their home away from home. They've played in it, slept in it, drank in it and stood by it after two break-ins. Found sound artists Mad Genius recently recorded the Hustle's van, remixing its hum and steel into a folk-rock ditty. Singer and guitarist Hugh Masterson was at the wheel.
