My memories are from the 80s and 90s, and my Dad was a guitar guy, too. He's gotten into mandolin since then.
I may have seen them at a bluegrass festival sometime back then, but I wasn't smart enough to pay attention in those days.
I've been listening to Seldom Scene and the Stanley Brothers, because the high tenor sound helps me get ready to sing the high notes in our Christmas cantata. We performed it this morning, but now I have the Seldom Scene singing "The Fields Have Turned Brown" on a continuous loop in my head, and sometimes out of my mouth.
Oh, well, at least it ain't Katy Perry.
