I recently decided to start exploring the Christian period of Bob Dylan's career, since it's a pretty sizable gap in my knowledge of the guy.
Stop one is the record Slow Train Coming. Two things stand out immediately: One, it is definitely Christian. Two, it is definitely a Bob Dylan record. Check out the track "Precious Angel" and try to tell me one bad thing about the music. For that matter, try to tell me how you'd write greater Christian rock lyrics, if you were setting out to do such a thing.
I particularly love the horns on this record. I can't think of any other Bob Dylan album where horns factor in at all. Also coming up huge is Mark Knopfler, who produced and plays lead guitar.
But the funniest thing about Knopfler's involvement is that Dylan never actually told him they were making a Christian record, and it didn't become apparent until he started laying down vocal tracks. Knopfler says he called his wife from the studio and said something to the effect of: "Sessions are going well. But... and I'm not sure about this... but I think we're making a Christian record." Classic.
(It also brings to mind one of my favorite Onion articles ever-- "Bassist Unaware Rock Band Christian.")
