What about Kevin Shields from My Bloody Valentine? He has tinnitus since 1991 but he hasn't stop producing and performing some of the most extreme music I have ever heard. I quote from an interview with the Guardian in 2013:
"Shields suffers from tinnitus ("it varies from mild to extreme") and has tendonitis in his fretting hand. He dismisses these conditions philosophically – "It's part of the job and we're all going to die anyway" [ ... ] "Initially, I was worried," he admits. "But I've come to treat the tinnitus as a friend. It filters unwanted sounds and actually protects my ears. It becomes your first line of defence against audible stress."

Anyone who wants to check what I mean by extreme:
I am baffled!
