I've found that the ones I wasn't as enthusiastic about early in my Mingus listening experience have grown on me over time--that is, Pre-Bird, Town Hall Concert (1962), and Mingus and Friends. The latter two grew in my estimation based on the expanded CD reissues.
I haven't listened to it in quite awhile, but the one that might fill the bill is Charles Mingus and Orchestra, which was made in Japan with a mixture of Mingus and Japanese musicians. When I got it I thought it was not good, but now I find I can't really remember anymore, so maybe I better listen again.
