Phelps was a dick & I loved him despite that fact. He would stay at my house when traveling through my neck of Southern Oregon w/ his (then) lady. Still never managed to remember who I was when I’d see him at a session, later on down the road. Drugs are one hell of a drug, ya’ know?
Anyway... Some needlessly loud shows I’ve seen... NoMeansNo, Nuerosis, Sleep, Shellac, High On Fire, Ministry, so many ear busters over the years. I owned a nightclub for a few years & as a result, saw some painfully loud shows in my painfully “intimate” (Read: SMALL) venue.
The single loudest thing I’ve heard at a show was a sound that Front 242 would trigger, seemingly at random & in conjunction with batteries of blindingly bright lights pointed into the face of the audience, sending fans scrambling for the lobby the 1st couple/few times it happened.
Downright cruel & abusive, it made an indelible impression on me. Clearly, I loved it; I still talk about it nearly 30 years later.
