High quality Christian blues is hard to come by, especially here in England.
Most of the good stuff I have come across is blues music by artists who are Christians rather than 'Christian blues'.
Eric Bibb is superb - As someone already mentioned - In my Fathers House is stonking. Also the Painting Signs album.
Blind Boys of Alabama - although more of a gospel vocal group their spirit of the century album and the stuff they did with Ben Harper is very bluesly in feel.
Walter Trout - on his Live Trout album he writes in the liner notes about how he was only able to go on stage after having a prayer meeting with his band and some of his stuff is overtly Christian in its lyrics.
Nobby Reed - all of his stuff is great. Very good electric blues.
Victory in Heaven Blues Band - they are good but do kind of rip offs of famous secular blues tunes. Worth checking out though.
Todd Agnew - his Reflections on Something album is class. (bluesy rather than 'the blues')
Los Lonely Boys - Christians who play SRV Tex Mex blues with pop melodies. Not all of their songs have Christian lyrics though.
The Word - A collaboration between Robert Randolph, North Mississippi Allstars and John Medeski jammin old school gospel tunes.
We got tired waiting for someone to do some decent blues music in church here in Newcastle, England. So we decided to have a go ourselves. **Shameless plug alert*** Check out some of our tunes at
