So much sadness. I accompany all the other comments about his drumming being another defining thing about their sound. In a scene where percussion is not appreciated, his skill level was astounding. Replicating it won't be easy, and continuing the creative process going forward will be even more difficult. So many of their songs start with "his" riffs.
Just...FUCK. You know?
I seriously hope that whatever he does in his life, he continues to make such impressive music. And I truly hope this doesn't signal the start of a domino-effect on what has been THE defining band in my adult life.
