Bit of back story for those not in the know: The show at Club Exit left me with, I'm guessing, 5% of my normal hearing ability in my right ear... because I didn't (repeat, didn't) believe in earplugs. Gradually it came back, but it was scary because I went from only hearing the lowest tones to gradually hearing more and more higher pitched stuff, but in a distorted "blown speaker" sort of way.
It took a week or so, but my hearing did finally come back to a mostly normal and tolerable state... though I learned, with the aid of an online hearing test, that my right ear was still slightly diminished in comparison to my left. I could live with that, but it still sucked because I'm a musician.
Anyway... it stayed at that point, slightly dimished on the right side, for some time... so I assumed that that's what I was stuck with and moved on with my life.
Well... just now I went back to the hearing test and have found that somehow, my right ear is now not only hearing all of the tones that my left ear can hear, it can hear the highest of them even better than the left ear, even to the point of hearing some tones that the other can't hear at all.
It would appear that, against all logic, The Wildhearts have caused the hearing in my right ear to be better than it was before.
Seriously though as a guitarist myself I hope that clears up for you.
