Joshua Redman “Timeless Tales (for Changing Times)” Warner Bros. cd Not the best Redman album of the 'nineties but with that band. . . still an interesting listen. Joshua with Brad Mehldau, Larry Grenadier and Brian Blade.  

The audio equivalent of comfort food for me. Antonio Carlos Jobim “Stone Flower” CTI+RVG King Records Japan SHM-CD  

John Hicks “I Remember You” High Note cd Solo Hicks. Great disc.

You can search Internet Archives or Old Time Radio for the various  treasury shows. I think there is not that much jazz. Your best bet for other jazz broadcasts is the Jubliee series. https://www.otrcat.com/p/jubilee

I'm definitely more interested in Mulligan as a baritone sax improviser, though I do think he was also excellent as a big band arranger and composer. He never could manage to sustain it financially long-term, but Mulligan seems happy when he's leading a big band on a spot basis. This is from his relatively later years; some might find it overly sweet, but personally I quite like it because it features plenty of Mulligan (and others) solos.
