Your Xtracycle may be a Grocery Getter or Adventure Maker by day, but by night.. it's the beat of the party. Check out Rock the Bike, a company that offers fully custom and do-it-yourself kits for "soul cycles," bicycle sound systems.
Also check out Shake Your Peace, a folk band:
touring on bicycles (without a support van) and using public transportation, powering its P.A. system with human/audience power via bicycle, planting a tree for each CD it makes, and more.
You can download or listen to a live stream of their music, here.
