When Denver singer-songwriter John Common started putting out feelers for an all-kazoo ensemble, many folks assumed he was joking. However, as Common proved with the project's debut at the Oriental Theater in February, he was absolutely serious about the admittedly silly idea. The People's Kazoo Orchestra doesn't exist to bring more attention to Common, who hopes it will be a self-sustaining ensemble without his involvement. Nor does it exist to produce groundbreaking music. The concept is simple: Everyone, regardless of musical talent, should get to experience the rush of playing music on stage in front of an audience. This effectively puts the means of production into the hands of everyone in town. You could almost write a manifesto about it.
