All five pieces the company danced last weekend at the Fox Theatre were handsome, and all had at least a drop of weirdness. The most interesting, least weird piece, Kevin O'Day's "Quartet for IV (and sometimes one, two or three ...)," set to a vivid contemporary string quartet by Kevin Volans, has four dancers involved in a consistently abstract lyricism undercut by odd angles of arms or foot or back. Never did the entire company appear onstage, but the dances, whether for two or 12, were at least interesting but most often completely absorbing.
