Over at the Comics Journal board, this little tidbit:
"I was searching through the iTunes music store and happened across the R. Crumb Fresh Air interview.* I had no idea that this audio content was available there. I did a couple more searches. The Master class in cartooning that Chris Ware and Charles Burnes did last year for the New Yorker is there as well. There are a couple of Spiegelman interviews also. If this sort of thing is your cup of tea, head on over."
