LOL! I didn't really start liking bluegrass until I was in college. My parents never listened to music much when I was growing up, but my Daddy loved the Sons of the Pioneers, and he used to piddle around on my brothers guitars. The two younger boys played guitar, one professionally for a short while.
When I was at Southern Miss, I went to a concert starring Lester Flatt and the Nashville Grass. I was hooked after that. I like the old timey stuff, I recently bought myself a CD of 'Seldom Scene', and just loved the soundtrack to "O Brother", though that was more 'old timey' than bluegrass. But I also love Newgrass. I have CDs from Skyline with Tony Trischka, and Allison Kraus.
When we were living in NJ, we used to listen to a folk music show out of Philly. They used to play a lot of bluegrass, and that's where I fell in love with Celtic music as well. They began playing some music by the Red Clay Ramblers from the music they did for a Sam Shepherd play on Broadway called "A Lie of the Mind" My favorite song was "Run, Sister, Run". I'll have to go searching for that music now!
