The notes for the Parker Benedetti Mosaic for sure (work of art) and Roswell Rudd's notes for the Herbie Nichols are also great but I've also a great soft spot for the notes to the Thad Jones/Mel Lewis, Anita O'Day, Larry Young and Jackie McLean. And quite a few others .
Commodore Vol 1 and Nat Cole are outstanding too in their craftsmanship !
Very honourable mention too to Michael Cuscuna's notes for the Woody Shaw. Written with great feeling.
