LOUDEST Concert and Tinnitus

This is a two part question.

1. What is the loudest concert (or event) that you have attended?

2. How long have you had tinnitus, is it getting better or worse and how are you dealing with it?

Personally, the loudest concert was UB40 at the Queen Elizabeth Theatre in Vancouver. Loudest event was drag racing at SIR (Seattle International Raceway) which was like sticking your head in a jet engine.

Regarding tinnitus. Over the past year or so I have noticed a constant high pitched "sound" in my ears. Mostly the left ear. At this point I don't actually know if it is constant or whether I just forget about it sometimes. I know use a white noise box when I go to sleep. Otherwise I tend to fixate on the ringing.
