Though not well known outside of Europe, the Franco-Austrian Gisèle Vienne has spawned a veritable industry of book-length analysis for her multidisciplinary performances and exhibitions. Crowd is typical of Vienne’s propensity for the morbid end of underground culture, by which she explores such popular preoccupations as communal experience and altered states. For the 18-person Crowd, the scene is a rave, with electronic dance music circa 1990s Detroit, Berlin, the East Village. But Vienne doesn’t want us to simply watch people disintegrating on the dance floor, she wants us to share their “intense emotions and heightened senses,” she has said. To that end, the piece messes with time. The beat goes on, but the dancers fall behind. The gap is our cue to enter. —Apollinaire Scherr
