Interesting topic for sure!
My first CD was a Flatt & Scruggs CD that my parents got me when we got our first CD player. The first song was the original 1949 version of “Foggy Mtn. Breakdown”. I was probably around 10-12 years old, or so. That’s when I really started getting seriously interested in bluegrass and banjo specifically, although I had grown up watching Hee Haw and listening to bluegrass and had some interest before that. It was a little while longer before I started learning much banjo (I was into guitar at the time).
Earl is pretty much my all-time favorite, and I admire his banjo backup during vocals or other instrumental breaks probably more than anybody’s. However, I will have to agree with a lot of what some others have said. He was not the first person to play a 3-fingered style. I don’t know how much I would have gotten interested in banjo had it not been for Earl, though. Basically all of my favorite banjo players first became interested in banjo listening to Earl (Doug Dillard, Jim Mills, JD Crowe, etc.).
