In 1937 it was hard to beat Allan Reuss, John Kirby, and Cozy Cole who played together on sessions by Billie Holiday, Lionel Hampton, and Teddy Wilson.
Art Tatum Jewels In The Treasure Box: The 1953 Chicago Blue Jazz Club Recordings - Resonance
This too was recorded at the Blue Note (the actual title is Jewels in the Treasure Box: The 1953 Chicago Blue Note Jazz Club Recordings). It is three cd's or three lp's of the Art Tatum Trio with Slam Stewart and Everett Barksdale.
I gave myself grief for purchasing this disc (and many others) which I could then easily stream. If I hadn't bought it, I wouldn't have been listening to it yesterday.

This is the one you want, but I don't see it currently on Discogs. I find Frog reissues to be excellent and this one does not disappoint: it has early recordings including the most useful one they cut as Andy Preer's Cotton Club Orchestra.
Cab Calloway started his orchestra by taking over the St. Louis band The Missourians who were an outstanding band and made some really good records on their own. I recommend them.
Personnel and recording dates are essential for me. However if this is the way of the world, it would seem an opportune time to get the Benny Goodman (RCA and Columbia) catalogue remastered and released.
