Patty Loveless and Ricky Skaggs, because they're from the part of the state where I grew up (eastern Kentucky) and their mountain sound reminds me of my father's favorite music.
Bruce Springsteen, because growing up in a little town and dying to get away I could listen to Born to Run, Thunder Road, Badlands, The Promised Land, etc., and know there was somebody out there expressing how I felt.
