Sarah Kaufman doesn’t just mean lofty ballet companies like New York City Ballet and ABT or lofty venues like the Kennedy Center: “In Dorrance’s pieces you might find a high-tech electronic floor that enhances the music of her dancers’ feet. Or maybe there’ll be a live funk-blues band, or flamenco dancers. Dorrance has knocked about, vaudeville-style, with Bill Irwin, the stellar clown. She’s made a site-specific work on the spiral ramp of New York’s Guggenheim Museum.”
