Roky Erickson was a pioneer of psychedelic music and founded a band called the 13th Floor Elevators, who were true pioneers.
Then he was diagnosed with paranoid schizophrenia. Which was probably a boon to his music and the lyrical imagery, but did cause a lot of personal problems for him.
He did get treatment, and his musical career never stopped. In 1982, he recorded a solo album called Don't Slander Me. This, the title song, is one of my favorites by him. This performance is one he did with a reunited 13th Floor Elevators.
