Hey Eric,
Here's one for ya.... The whole CD/soundtrack from Mark Twain, A Film by Ken Burns
is worth consideration. There are mostly instrumentals pieces on it, but the music is very American, country, gentle, raucous, some traditional, guitar, piano, fiddles, harmonica, and to me, many would fit the mood and content of BBM Radio. I got my copy on Amazon, but if you have a CD player or somethin' to listen to it on, I could bring it with me to Alberta. Maybe you've heard it already since you listen to a lot of stuff like I do.
I'm also glad to hear Joe Euro on BBM Radio. He lives not far from my folks in Washington.
Cuts off the album I suggest are Howl, Wagoners' Lad, The Falls, Ties That Bind, Hard Times (either version) and a banjo/guitar cut of Swing Low Sweet Chariot.
