Ooh, good ones @slaw. I should have included Mary Gauthier, whom I had the pleasure of seeing live in a small Portland club last year. She was fantastic (very funny, and a good story teller), just her voice, her acoustic guitar (she’s a very effective player---very dynamic), and her wonderful songs. She was joined on harmony vocals on some songs by the woman whom often opens for her on the road (as on this night), don’t remember her name.
But for Pete’s sake, how could I forget Levon Helm?! After leading The Band following the departure of J.R. Robertson, and following the deaths of Band pianist/singer/songwriter Richard Manuel and bassist/singer/songwriter Rick Danko, Levon recorded and released two albums, Dirt Farmer in 2007 and Electric Dirt in 2009, both winning him Grammy Awards. Not bad for an Arkansas hillbilly. ;-)
