John,
I believe that their singer/primary songwriter is called John Croslin and he quit the biz due to stage fright. That's a shame,too, since his songs are finely crafted, original but not mannered and employing harmonies that I frequently find arresting in a quirky way. He made a brief comeback in a band called Fire Marshalls of Babylon (or something similar) some years back, but IMHO that never touched the quality of his work with The Reivers.
As to the more alt., less country, I wouldn't argue with you. I'll just dump it all under Americana and call it a day. Enjoy your new purchase. (Sorry to see that shipping wasn't included.)
