You can try the Good Question! Podcast. My good friend John Farrell is a professor of literature at Claremont McKenna, and he and I record an amateur podcast on a wide variety of subjects. We created the podcast after some of John’s students said they like hearing professors talk and express different points of view. (Note: the audio quality improves after the first few episodes.)
For aesthetic bliss, you could check out the wonderful musician Sean Hayes playing at Spaceland or Jolie Holland singing “Mexico City”. Best of all, check out my wife singing Brahms, Schumann, or Mahler.
