His last release, as far as I can find, was in 2002, Chico Freeman e Guataca, Oh By the Way.
Not as good as The Emissary, but still has some nice tracks on it.
The Emissary, on the Clarity label, is very well recorded.
Tradition in Transition on the Elektra Musician label (from around 1982) is an early favorite of mine.
Diverging a bit from straight ahead jazz into jazz/world fusion, the more recent recording The Emissary is excellent.
A couple of years ago, I saw Chico Freeman with Geri Allen, Richard Davis, and Andrew Cyrille at Jazz Standard.
Well to each their own of course but I have come to really like every session. . . Massey Hall. .. Thad Jones. . . Hazel Scott. .. John Dennis. . . Jackie Paris. . . all those bones. . . man, this is jampacked!
I'm with you, great box--in addition to the Bohemia and Massey Hall sessions, I'm partial to the Thad Jones sessions, the Jimmy Knepper with Joe Maini session, and the unreleased session with Gene Shaw, Shafi Hadi and Pepper Adams.
He doesn't disappoint me. His best recordings (in my opinion) are Chasin' the Gypsy, Layin' in the Cut, Live at Baker's Lounge, and (under the leadership of Ronald Shannon Jackson), What Spirit Say.
You might want to get allaboutjazz New York off the allaboutjazz website (about the most thorough day by day jazz listing for New York), and also pick up a copy of Time Out New York when you get there. There's usually something totally unexpected that pops up, so stay flexible.
In addition, you are only nine blocks south of the Jazz Record Center, which is on 26th Street, off of Seventh Avenue.
