Great reads, thanks for sharing. It's like you can see him getting angrier and more disillusioned with jazz and the industry in general with each session. I also learned a new racist slur from that last one!
Umm, I don't know about that. I've definitely heard 2 of my black friends disparagingly refer to other black people as uncle tom's within the last several years. That book, or at least tangential references, is apparently still in cultural memory. FWIW, this is the upper midwest, that slur might not be a thing on the west coast, I can't say.
For GP, based on the novel "Uncle Tom's Cabin" [1]. The book was abolitionist, but a quick read through of the wiki should give some background on why the title characters name is now a slur.
