I wasn't including Roland Kirk in the "older stuff" category; I was just noting the funny coincidence that I happened to be listening to Kirk's version of a song about Pres.
Thanks for the many great suggestions of specific titles! I've already put the Ellington, Bechet, Eldridge, Webb, Pee Wee Russell, and James P. Johnson on my wish list.
Any other suggestions for Bechet albums to pick up?
