Religious music for less than devout

May I second "Christo Redemptor" this time by Charlie Musselwhite. His version is much longer (11 minutes) and has many changes in tempo. It is a very complex and sophisticated piece

This thread will cost me some funds as I send all my money to Amazon.

Thank you to every one for their recommendations. I had 4 CDs arrive this morning, I have been "mining" this topic. The suggestions are not going to waste.

Blind Faith - Presence of the Lord

Carlos Santana/Mahavishnu John McLaughlin - Love/Devotion/Surrender

Mississippi Fred McDowell - Lay My Burden Down

Dr. John - The Night Tripper (Gris Gris) (Voo Doo is a religion, I believe)

@pfeiffer It seems to me that Imagine is the antithesis of religious music since he is asking us to imagine what it is like with no god, no religion. I've always liked it as a song. I never liked the assumption that things would somehow be better if there was no god. 

Another song along those lines (which I also like) is Joan Osborne's song What If God was One of Us. Like Imagine there seems to be an irony that the artist completely missed.

Osborne says:

What if God was one of us?
Just a slob like one of us
Just a stranger on the bus
Tryin' to make his way home?

To a Christian these lyrics are a little shocking. Not because they are somehow blasphemous but because what she is asking for and looking for is exactly what Jesus was. According to Christian theology Jesus was God and also one of us. A stranger. Poor. Common. Probably filthy and hungry most of the time.

I always wondered if Osborne was aware of this irony.
