Sadly, Roky Erickson (13th Floor Elevators) has passed.

He wrote and sang some great tunes in the Elevators and as a solo. My favorites were "Starry Eyes" as a solo and the one big hit with the Elevators ("You're Gonna Miss Me"). He was also the subject of a documentary about his long personal struggles. One of the pioneers of psychedelic rock.
