Catching up with the rest of you again. And glad to be back on track with the OP -- jazz.
Let me offer this as a possibly surprising and under appreciated jazz musician, Andre Previn. I say that knowing his "My Fair Lady" album was alleged to be the top selling jazz record for some period of time. But after that died off, almost no mention again. He focused on Broadway show tunes with several albums devoted to individual shows. Of course it helped that he was accompanied by top flight musicians. To me he was certainly more than a classical conductor.
