Over the last few years I've been fortunate to stumble upon some great podcast shows related to illustration, comics, animation and art. It has been an education listening to these, and best of all they are free!
I feel an enormous amount of gratitude while writing this and thinking about all the people that so generously gave their time and energy into creating these. To keep it short, here is a list of my three favorite art related podcasts. They are the ones that I've learned the most from and check regularly.
