Tap phenom Savion Glover finds nothing odd about doing two sets a night with his fellow "band" members--spoken-word artist Reg E. Gaines and saxophonist Matana Roberts, a Chicago native--in a space that seats 150 people. "This is what we do," the laid-back Glover says over the phone. "I've performed in clubs for 20 people--and in stadiums." For audiences, however, the chance to see Glover, Roberts, and Gaines (who wrote the book for the Tony-winning Broadway musical Bring in 'da Noise, Bring in 'da Funk) in an intimate venue is something special. The concept here is to keep the spirit of John Coltrane, who died in 1967, alive by improvising on his standards: A Love Supreme, "My Favorite Things." But though Glover is a superb technician--his tap arpeggios recall Coltrane's "sheets of sound"--the show's point is not virtuosity but soul, not duplication but reimagining a legacy. Opening performances Tue 2/14, 7 and 9 PM. Through 2/19: Wed-Sat 7 and 9 PM, Sun 3 and 6 PM, Theatre Building Chicago, 1225 W. Belmont, 773-327-5252, $40.
