I grew up on country music, thanks to my dad and his Appalachian home. There was a wonderful 3-part documentary about country music that's never been released to my knowledge on DVD. It's title was Lonesome Road, Lost Highway, something like that. My dad always wanted to get to the Grand Ole Opry, but to my knowledge, he never did.
I like Hank Williams, Dolly Parton, Emmylou Harris, probably more, since I've listened to a lot for Christmas Up The Holler. And I love the soundtrack for Nashville, one of my favorite films.
