Lacy, Rutherford, Stevens, Parker, Bailey. I think those artists were perfectly documented by Martin's efforts, though certainly there were a lot of others who benefited from his keen ear and dedication.
I was glad to have a few nice communications with him over the years, and he participated in the WPI Jazz Institute zoom roundtables occasionally as well.
As for the stock/catalogue, my assumption is that his surviving partner is sorting through grief and logistics as best she can. As I recall she is older and this is probably quite challenging for her. I have no intel, but can only assume this is the case. There are a few Emanem CDs I never picked up and would like to. Hopefully they find a way over here eventually (de minimis cancellations be damned!).
