Hart grew up in Baltimore and came through the Berklee College of Music pipeline, which is where he connected with Roy Hargrove — a partnership that would define both of their early careers. The two had an almost telepathic rapport, and Hart appeared on several of Hargrove's early Blue Note dates, lending an urgency and heat that matched Hargrove's own trumpet brilliance. If you've heard those records and wondered who that alto player was burning alongside Roy, now you know.

Hart's own debut, Don't You Know I Care (1992), announced him clearly and without ambiguity. The playing is direct, rooted in the bebop tradition but with enough grit to keep it from sounding academic. His tone on the alto is round and full — not the thin, aggressive edge some players go for, but something warmer, closer to the sound Cannonball Adderley was getting in a good room. That's not a casual comparison; Hart has cited Cannonball as a touchstone, and you can hear it in the way he phrases, swinging hard but always with a melodic intelligence keeping things in check.

The mid-90s were busy for Hart. He kept releasing albums on Novus and continued showing up as a sideman across a wide swath of recordings. What made him distinctive in that period wasn't just the technique — plenty of Berklee graduates have technique — it was the emotional directness. He's not a player who hides behind complexity. When he plays a ballad, it sounds like he means it. When he digs into an up-tempo blower, there's no showboating for its own sake; the energy serves the music.

Hart eventually moved into teaching alongside performing, spending time at Queens College in New York, which is a path a lot of serious players have taken. Some people treat that as a retreat from the scene, but Hart kept recording and gigging. His playing in his later years has actually deepened — there's more patience in his solos, a willingness to leave space, that you didn't always hear in the early records where the impulse was to fill every bar.

He's not a household name outside of serious jazz circles, and that's a gap worth closing. If you're working through the post-bop alto players of the 1990s and you've already spent time with Kenny Garrett and Steve Coleman, Hart belongs in that conversation. Different approach from both of them — less angular than Coleman, less pyrotechnic than Garrett — but no less committed. Start with the Hargrove collaborations if you want to hear him in his natural habitat, then circle back to his own records.
