I'd be interested to know what you consider to be the most impressive (or maybe just historic) examples of jazz musicians playing as lead on records of classical music repertoire in a classical setting (i.e. not the AEC throwing in a Monteverdi piece or Ornette Coleman quoting Stravinsky; and not Jacques Loussier type classical jazzed up).
Some obvious examples would be:
Keith Jarrett on ECM (various examples here); and
Wynton Marsalis' Haydn, Hummel, L. Mozart: Trumpet Concertos from 1983.
