Dead at 69. Pivotal part of the Downtown NY No Wave scene of the late 70s and early 80s. You can hear his influence in Sonic Youth, Swans, Band Of Susans and a lot of the drone/atonal experimental music that followed from that scene. Challenging stuff, still, but in the right setting/context a rewarding listen. A friend of a friend once played in one of his 100+ guitarist orchestras for a one-off performance (think it was #13), and said it was a lot more fun than the deafening wall of noise might suggest. Symphony No 6 (Devil Choirs At The Gates Of Heaven) is a good introduction, and some of his shorter pieces like "The Ascension" and stuff he did with Theoretical Girls are well worth a listen too.
