Once again I've probably blown the genre, but I have Joe Nolan's song "Get Behind Me Satan" (from his self-released album, King) in my iTunes library as Christian Blues. I'm also making it the Song of the Day! It's very bluesey in rhythm, lyrics, and arrangements. And the idea behind the lyrics is very Christian. Speaking of lyrics, it has a great line: My silver sword is shining like holy Detroit cold ... Jeepers, that's great! Manly yet poetic. According to his Website "Detroit-native Joe Nolan's sound combines the soul spirit of the Motor City with a poet's ear for the rhythmic beauty of words." Yup, I'd agree.
I haven't heard anything else from Mr. Nolan, though. That was the only song of his I found to download from the old mp3.com site and haven't found anything since. If you can find it, grab it.
