This is how I know God has a sense of humor: Warren Barfield is one of the best live acts I've ever seen. He's a Christian performer and when he played at our church, he and his guitar made a joyful noise unto the Lord, all right. Were he a secular performer, he'd probably be at least as popular as Jack Johnson (and loads more entertaining, with his sense of humor and his blues/soul/funk spin). But God called him to something different, and there he is.
Not that I'm an expert, but I've seen Nanci Griffith, the Who, Rush, Paul McCartney, Neil Diamond, John Denver, Yes, Jimmy Buffett, Ringo Starr and some other fairly well-known and talented folks who put on terrific live shows, and Warren Barfield was every bit as entertaining. No techno garbage, no laser show, no wall of sound, not even an electric instrument -- just him and his guitar.
So buy his stuff, including the album that comes out in May. Don't believe how great he is? Check out his version of "Sitting on the Dock of the Bay." That should convince even people who aren't Christian music fans.
