Roky Erickson (https://www.youtube.com/watch?v=BF5xZawdYZ4), at 71 years. I suspect that the porn-shop job didn't help, but yah, best wishes and, I hope, good travels, man.
He got dealt a bad hand and I?m frankly impressed he survived as long as he did. A real one.
There was so much really fucking great garage/psychadelic music out of Texas in the 60s (Moving Sidewalks, Sir Douglas Quintet, etc), but the 13th Floor Elevators were the fucking best. and as bonus cool, Roky gave a big boost to Alejandro Escovedo, who fucking rocks.
The normally execrable "Sound Opinions" actually managed a decent segment (https://www.soundopinions.org/show/707/) on Roky last week. I certainly had no idea that Janis Joplin was almost (for certain values of 'almost') an Elevator.
