I enjoyed the Netflix series "Pretend It's a City" (from 2021), where Martin Scorsese lets Fran Lebowitz answer questions on a range of subjects. Full of witty one-liners, and very New York. Seven half-hour episodes, quite entertaining.

I really enjoyed the two recent episodes on The Rolling Stones on the "The Rest Is History"-podcast. Historical and social context, as well as lots of interesting facts about the band. And (as always) articulate and witty hosts. A joy to listen to.
