Well, there's always Eva Cassidy. But, I continue to recommend the Stone Coyotes, a small rock and roll family band fronted by a 50-something singer/songwriter (Barbara Keith, her husband Doug Tibbles and his grown son). Church of the Falling Rain, Situation Out of Control, and their latest, Born to Howl (4 1/2 stars with a check at allmusic.com). All should be available at Amazon, or you can order from the band at stonecoyotes.com I think.
