Despite if it's from the worst album by Black Sabbath;
despite if that album is the last of that part of their discography which was forcibly included by the labels despite being Iommi solo albums;
despite if all the then-band members hated the rushed production and mostly not being able to hear it before the released;
Despite it all it's a stunning killing piece

(small offtopic to MooCHa: remember those dark ambient songs you linked to me? I have to say I didn't liked them. Sorry....)
