The Ginger Ninjas are on a 5000 mile tour from Northern California to Southern Mexico, carrying all equipment on their bikes, including this 1000 watt human-powered sound system.
The human powered PA makes extremely low-impact music touring possible, sans automobile and sans electric outlet; it also makes it possible to play music in any location.
