Savion Glover's newest production, OM, is as much a mystical experience as a dancing one. The performance, which spans about seventy minutes with no intermission, begins with a lengthy jazz recording of what I think is Calling by Kenny Garrett, very improvy -sounding and full of saxophone. During this pre-performance period, the audience views the front of the stage lined with small bulbs that seem to flicker in the half-light with a head of Buddha on one side. Finally the curtain is raised, revealing the stage set with hundreds of candles of all sizes, and photos of Glover's spiritual mentors, some dance figures like Gregory Hines and others more spiritual like Gandhi. I'm not sure where Michael Jackson fits in. Glover, minus his trademark dreads, stood on a small platform in the center where he remained for the entire performance.
