Michael has recorded with Braxton and Noah Howard, among others, and was Steve Lacy's pianist for a couple of years in the mid-70's. Check out the Lacy/Smith duo album Sidelines on Improvising Artists for one of the best Lacy-plus-piano recitals on record.
I know Michael's music pretty well because he spent a year in Atlanta in an odd artist-in-residence gig back in the 1990's. We played together a fair amount, and I issued two tunes from a recording session we did back then on an otherwise fairly mediocre CD I put out 20 years ago.
Haven't played Sidelines in a while, but I remember it as a very good one.
