On a sunny Sunday afternoon last July, several hundred people crowded the Dequindre Cut, a popular recreation path in Detroit, to see a dance. The performance, one of three public dance labs programmed to accompany “Here Hear,” the Cranbrook Art Museum’s celebrated exhibition of Nick Cave soundsuits, included music by Frank Pahl and choreography by Biba Bell. There is no telling what, exactly, the audience expected. What they witnessed was a distributed dance, a de-centered performance event, in which any vantage point along the Cut’s long, linear footprint offered a different view of different groups of dancers, some of whom slinked by in sinuous silence, while others posed, elegant and remote, above the crowd. Others danced a mannered duet involving the ritualistic exchange of their black or white soundsuit costumes, and the rest, by the end, were dancing in furious, ecstatic unison. When all was said and done, no one present had seen a complete dance, or the same dance. Everyone, however, had seen a dance by Biba Bell, an artist who specializes in the unexpected.
