I’m looking to get this introduction to Celtic Frost’s ‘Morbid Tales’ turned in to a choir - the kind of voice-of-angels choir that one might hear during a beatific vision. I’m guessing this could be a pretty simple process of just loading it in to some programme with a plug-in of some description, but it’s beyond me. Any of you good folk out there know how to do it?
