Yes, sprinkled all over the country are wonderful players you'll never hear.
I was on the road once in Tulsa, Oklahoma and our guitarist said we should go out to an airport Holiday Inn lounge and hear this guy Tommy Crook. The guitarist was reading an interview of Chet Atkins and the interviewer asked, "Who does Chet Atkins listen to when you listen to guitar players?" and he said, "Tommy Crook".
So we went and listened to this guy at an airport inn playing a solo act and he played his butt off. We later asked him why he didn't have greater exposure and he said that he hated to travel.
A guy I've never heard of having wider exposure is Aubra Graves (sax). Man this guy is tasty. Here's a link but he has a number of tunes on YouTube.
