I seem to have documentaries pouring out of my ears at the moment, including a whole lot of free ones on Youtube.
I stumbled upon a series done by Art Documentaries that briefly looks at what goes on in the life of different artists. I haven’t finished watching all of them, and it seems that these might be previews. Regardless, you get a 30 minute preview (2 x 15 minute episodes) that’s still damn good on it’s own. You can also check out the Art Documentaries channel for additional videos.
