From bicyclemusicfestival.com:

The Bicycle Music Festival is a 100% bicycle-powered moving music festival, where audience members riding bicycles-in-place produce electricity for the sound system. In between venues, musicians like Rupa and the April Fishes and Jazz Mafia perform Live On Bike from a mobile stage.
