1971 Steve Miller Band Milwaukee
1990's ish Robert Palmer this was the killer. We were there with another couple, and no one had the sense to walk out, including me. At the Orpheum in Minneapolis when Dylan owned the theater. Not his fault.
2005ish drive-By Truckers in St Paul. I had the sense to walk out of this one. Arena's are mostly terrible for sound.
Had a terrible onslaught of tinnitus in 2007-8. Learned I had hearing loss and started wearing hearing aids. I used an expensive treatment repped by my audiologist. Whether it helped or my symptoms lessoned over time, not sure. But I listened to the program every night for years and it gave me a sense of being in control.
I can always tell when I sit down to listen to music and have forgotten to put them in. It's a volume issue, but mostly a quality of sound benefit for me.
