Don't think this has been mentioned yet itt:
You're Gonna Miss Me - Just gonna copy and paste the description from Netflix (yes, it's available on Watch Instantly as well):
It's not easy being a pioneer. For proof, just watch this film about Roky Erickson, whose band, the 13th Floor Elevators, coined the term "psychedelic rock" in the 1960s. Targeted for his advocacy of pharmaceuticals, Erickson was busted for possession of a single joint in 1969 and spent three years in an institute for the criminally insane. This film covers his rise and fall, as well as his family's efforts to help him get his life back on track.
Haven't watched it yet, but sounds interesting and intriguing.
