In dance, the body is substituted for the voice, the urgency of muscle and bone taken as universal, various languages codified in the form of techniques. All this replaces the dominance of the mouth and makes the lungs more of an engine than bellows. Joe Goode Performance Group takes on this trope in "Hush" at Zspace, Oct. 3- 5, an evening-length work of six interlocking stories about silence and silencing developed from narratives donated by prior audience members and the San Francisco community. The resulting dance theater piece imagines silence as a conduit to self-discovery and empowerment. With a soundscape inspired by movie background noises devised by electro-acoustic sound artist Sudhu Tewari and a score by Bay Area musician and composer Ben Juodvalkis, don't expect a quiet evening out. Do expect a performance that strikes a balance between the thoughtful, the theatrical, and the purely athletic.
