I've just been browsing this thread and found a number of recommended titles that I missed when it was current, so I thought it might be worth bringing up for others to check out again.
A few more recommendations (apologies if I missed them being mentioned previously - this thread runs 21 pages!):
Tiny Grimes with J.C. Higginbotham: Callin' the Blues (OJC 191)
Stan Getz/Zoot Sims: The Brothers (OJC 008) - Two sessions - one is a blowing date (albeit with good tunes and arrangements by Gerry Mulligan and Al Cohn) with good playing by Allen Eager, Brew Moore, Al Cohn, Zoot Sims, and Stan Getz - a chance to listen to and compare the five tenorists. The other date is a sextet with Al, Zoot, Kai Winding, George Wallington, Percy Heath, and Art Blakey.
Carmel Jones: Jay Hawk Talk (OJC 1938)
Pee Wee Russell: Swingin' with Pee Wee (Prestige 24213) - The Portrait of Pee Wee and Swingin' with Pee Wee (very fine Buck Clayton) dates combined - not to be missed.
The Red Rodney Quintets (Fantasy 24758) - I actually only have this on an OJC LP which is titled Modern Music from Chicago and includes the Fantasy sides with Ira Sullivan. The CD adds an earlier date with Jimmy Ford which I haven't heard. The Sullivan date is well worth listening to.
The Lee Konitz Duets (OJC 466)
