Love this mini-doc on John Baldessari, voiced by Tom Waits (who since hearing this - can't get Heath Ledger's Joker performance out of my head when hearing Tom Waits talk).
I really enjoy these kind of doc's which squish 30 minutes of info into 5 minutes, and giving us way more insight into a person's character than a dreary talking head. It's like stepping into their brain for a moment.
