This is a fantastic interview with Padgett Powell (https://en.wikipedia.org/wiki/Padgett_Powell), a writer of the Southern tradition. IMO, the two things that make it great ar how candid and fluid Powell's answers are and the hilariously Newspeak of the interviewer's questions.
Powell was Don Barthelme's student, his analysis of Barthelme's main thrust here is worth the read alone. If you want to dig deeper on this point, here's another interview with him: https://www.vice.com/en/article/vdxyd8/padgett-powell-is-ame...
Flann O'Brian, mentioned briefly by Powell is an interesting character, too: https://en.wikipedia.org/wiki/Flann_O'Brien.
