Fossil Fool, the Bike Rapper, and drummer Joel Elrod perform while cruising the streets of the Mission District in San Francisco at the Bicycle Music Festival held in June, 2008. Joel keeps the beat on a SPDS drum machine mounted on the LiveOnBike rig, a modified Mundo Cargo Bike, whose signal is sent wirelessly by a Shure bodypack microphone to the Choprical Fish (Fossil Fool’s bike) and then wirelessly amplified by two other Soul Cycles rolling alongside.
