I might add another couple of words of encouragement here.

What most people are literally dying for is beautiful instrumental playing, especially if it's at the virtuoso level.

So let's say you're a phenomenally good jazz guitarist.

If you go play in a restaurant or club with backing tracks but your solo playing is heavenly and divinely inspired no one's going to give a flip that you're using backing tracks, they're just going to be in a trance because of the level of your instrumental playing.

People are dying to listen to people who can actually play.

If you want to use some backing tracks to back yourself up they're not going to care trust me.
