Black Sabbath – Black Sabbath (from the album Black Sabbath 1970, Vertigo) You can pretty much pinpoint the start of doom metal to the opening riff of Sabbath’s title song on their self-titled album. Tony Iommi dropped his guitar tuning down one and a half steps out of necessity, but what came out of it was a sound that still defines heavy music today. Ozzy Osborne,  Iommi, Geezer Butler and Bill Ward changed music with one album. One of the darkest sounding songs of it’s era still conjures evil to this day.
