My buddy Gabe Dominguez fronts a music group called Shake Your Peace. These guys are touring Utah on bicycles this month, carrying all their food, clothes and instruments on their bikes the whole way. These photos are from a show they played at the One World Cafe in Salt Lake City.
See that teeny wooden box with speakers in the background? That's their amplifier, made from used car audio parts. This amp is even more unique becaue it doesn't plug into a traditional power outlet. No, sir! This amp is pedal-powered! Yeah, my buddy James is riding the bike (with his killer tiny vest) and, in turn, powering the sound. If he were to stop pedaling, the amp would die down and there would be no sound.
