OK, here's a small portion of my list:

Mississippi John Hurt
Bessie Smith
Billie Holiday
Ella Fitzgerald
Jim Kweskin and the Jug Band
The Carter Family
The Beatles
Muddy Waters
Woody Guthrie
Uncle Dave Macon
Kitty Wells
Patsy Cline
Bill Monroe
Hazel and Alice

I am fortunate to have seen a lot of my musical heroes (mostly thanks to my mom who dragged me to all kinds of concerts when I was too young to protest!).
