Forgotten spell rehearsal II-IV.

There was a very talented raw black metal arist working under psuedonym Angra Malakh. I am a big fan of his works and wanted to listen to them. Sadly when I was trying to find his demo's "Rehearsal II" , "Rehearsal III ...of the diabolical..." and "Rehearsal IV. The storm of crying funeral souls" I found nothing except photo's of demo's and last.fm page that would not play music. 
Does someone knows how to, and if it's possible to turn spectogram image into sound? Its only that i have right now. An image of spectogram of those demo's.
