Russ, maybe the thing to do at this stage is to simply tell people what you want to do, what you want to play, and let the chips fall where they may..?
I’m sure with your reputation and ability, you will get at least a few jobs that let you be you, and even though it won’t be back to backs, the charge you get from playing live can energize you and make a break from the cloistered studio life. Especially if you finally get to play only your favorites!
Every musician you admire took this step, to say that they would only play what they wanted. The greats still kept playing live, and found an audience for what THEY felt was good. If you can contemplate stopping altogether, you can also contemplate this alternative...
