The Raveonettes at Mercury Lounge NYC spring 2005???
Small room, low ceiling - band cranked up to 11 or 12!!! I think they wanted to hurt us.
Ears were ringing for 2 days.
I was a DJ at The Peppermint Lounge way back when BUT we never hand any band play nearly as loud as them. Of course it was a gigantic venue compared to Mercury - but Jeez!!
As far as tinnitus, I notice in the winter ( dryer air?) that I get some background noise almost like tape hiss or test tones that comes and goes.
Luckily nothing that normal listening levels can't override BUT I'm no spring chicken and I have spent many years working in clubs, arenas, recording studios, mixing /editing rooms, etc. I'm surprised how good my hearing still is.
I don't know how long my luck will last....
I use a dB app on my phone now if I doing "critical" listening at home to help monitor the enjoyment
