Just watched a documentary called You’re Gonna Miss Me over the weekend.  It’s about Roky Erickson, who was the lead singer for the 13th Floor Elevators in the late 1960’s.  They were one of the pioneers of the psychedelic rock sound.  The documentary looks at Erickson’s struggles with drugs and mental illness and his family’s attempts to get help for him.  A very strange and sad situation.  It’s streaming on NetFlix if you’re interested.  Here’s the trailer on YouTube:
