How about a fresh spin on some reggae?
Yeah, we all loved Marley when he Shot the Sheriff, but the Reggae Cowboys got good "riddem" too:
SeeqPod - Playable SearchTry the Reggae Cowboys!
At their website, you can listen to several mp3 selections - I really love their take on Outlaw Man.
The Reggae Cowboy site also points out some good starting places to learn about the historical black cowboy.
Of particular interest for me is the story of "Stagecoach" Mary Fields. I love histories about outlaw women.
