I guess I would be considered a fan.
We don't go to a lot of festivals - but we go see local bands and I listen to a local Bluegrass Radio Station - WOBO if you want to listen to it online:
https://www.wobofm.com/I also was the Chairman of the Music Committee for the Cincinnati Appalachian Festival for a dozen years and got to see a lot of music in the process.
I play clawhammer banjo....my wife plays guitar and was in two Old Time music bands (pre-bluegrass stuff like Carter Family, Loovin Brothers.
We have been fortunate to see a number of great artists before their passing. Doc Watson, Hazel Dickens, George Shuffler, John Hartford, Tony Rice.
One person that was not so famous that I didn't get to see in person was Dawn Sears.....what an incredible voice!
