John Cale - Paris 1919 http://www.youtube.com/watch?v=q5YHqWqhFkU It's so good that I actually think it's from a better place than earth..   (No religious intent)

Odd that no one has mentioned Samla Mammas Manna. Some might argue that they are more of a Swedish "progg" (ie. left wing) than a progressive rock band, but I do not agree. They're more of a avant-folk progressive rock band in my ears.   I recommend their self-titled album Samla Mammas...
