Keith Hennessy was born in a mining town in Northern Ontario, Canada, lives in San Francisco, and works regularly in Europe. He is a performer, choreographer, teacher, and organizer. Hennessy directs Circo Zero Performance, a laboratory for live performance that defies genre and expectation. Rooted in dance, Hennessy’s work embodies a unique hybrid of performance art, music, visual and conceptual art, circus, and ritual. He is the instigator of the Turbulence (a dance about the economy) project. Hennessy's performances are embedded in leftist and anarchist social movements; his career began in anti-nuclear juggling, acrobatics, and vaudevillian comedy.
