I heard three variations of the group live:
Marty Ehrlich, John Purcell, Howard Johnson, Rufus Reid.
David Murray, John Purcell, Howard Johnson, Rufus Reid.
Greg Osby, Gary Thomas, Lonnie Plaxico, (the guitarist's name is escaping me at the moment).
All three groups were excellent, but the one with David Murray was the best (they played all of the material from Album Album in superior versions).
