I haven't seen this picture of Roky Erickson tearing it up before. He looks like he's hitting some unknown territory there. And Stacy is just checking him out as he does it. I really feel like Roky Erickson is the Greatest Rock Vocalist that Ever Lived. He smokes everybody. Roky Erickson 13th Floor Elevators; 'nuff said!
Stacy Sutherland is on record stating that Roky Erickson used his voice like a musical instrument and that vinyl never completely captured his sound.
