Roy Orbison This is hard for someone my age to answer as there have been quite a few, a lot of times it is just a couple songs, like with Elvis when he sings Amazing Grace, Dixie, or his Christmas album. I like Kid Rock when he goes back to his country roots, but nothing else he does, so I cannot count him as great.
Jacoby Shaddix from Papa Roach, Billy Idol, David Michael Draiman from Disturbed, Dave Wyndorf from Monster Magnet, and Chris Taylor Brown from Trapt all good singers in my opinion INDEED peoples' LOL :)
I'd have to give that accolade (like the big word) to Barbara Streisand. Her vocal range rivals any opera singer (she could of been one) and the purity of her voice is awesome. Beyond that I love "The Way We Were", other of her hits.
hank williams (jukebox king from LA to CAROLINA) that only lived to be 29 and still thought of as the king of country music. charley pride, johnny cash, john fogerty, randy owens, randy travis, george jones, conway twitty, o wait you said one? i cant help you sorry opps i forgot merle haggard..........
