I there someone else like Jackie Leven?

Lately, I've been listening to a lot of Jackie Leven's music. I only found out about him by reading Ian Rankin's novels with Inspector Rebus. I wonder if there is any music of similar beauty and seriousness out there. Leven's "Ellegy for Johnny Cash" and "Shining Brother Shining Sister" have moments that connect with me more than other music out there. I also listen to Richard Thompson, Beth Orton, Greg Brown, John Stewart, John Prine, Steve Earle and the Subdudes, but these are more well known artists.
