OK, for the pinheads who do not get it, even though I have said it before: "Stormbringer", for my purposes, was taken from a great song by Deep Purple, from the album of the same name that was released in 1974. David Coverdale (later on, of Whitesnake) shared lead vocal duties with Glenn Hughes. If you want to rock out, you can listen to the original Deep Purple "Stormbringer" here.
No, I have never read the fantasy novels by Michael Moorcock. The album had some good moments, but I liked their previous album, "Burn", much better.
