Danny Gregory, author of Everyday Matters and The Creative License, has a new book coming out in the next month or so called An Illustrated Life. There are several artists featured in this book and he has been doing podcasts with some of the artists to talk about their artwork. The podcasts are only about thirty minutes each and very informative. I like to go to the artist's website and look around at their work while listening.
I encourage you to spend some time on Danny's site and his books are excellent too!
