Bill Monroe was something pretty unique in music. He "invented" bluegrass music, which is a folk music involving improvising on a melody, each instrument taking a turn while the others accompany. Sounds all egghead there, but it's really just a good time acoustic dancing music that I would argue gets folks as crazy dancing as any good rave out there. That's why I like it.
Monroe pulled together this new style from older ones, and his Blue Grass Boys took it on the road for years and years in the years around and after WWII. An hour of these tunes, and you will be panting with glee!
Oh, and I think next time back to the electric stuff. But this show and the last one were totally worth the detour! :)
