Terence Mckenna - Something is happening.

A happening is a performance, event or situation meant to be considered art, usually as performance art. Happenings take place anywhere, and are often multi-disciplinary, with a nonlinear narrative and the active participation of the audience. Key elements of happenings are planned, but artists sometimes retain room for improvisation. This new media art aspect to happenings eliminates the boundary between the artwork and its viewer. Henceforth, the interactions between the audience and the artwork makes the audience, in a sense, part of the art.
