57. 'Black Sabbath'
Warner Brothers, 1970
While the hippies huffed flower power in 1970, this Birmingham crew preferred sulfuric fumes. The album that arguably invented heavy metal was built on thunderous blues-rock – see "The Wizard," which suggested the same juke-joint Lord Of The Rings obsession Led Zeppelin had. But the title track, with its famously downtuned Tony Iommi riffage, would define the sound of a thousand bands. And by the time Ozzy Osbourne sings "my name is Lucifer, please take my hand" on "N.I.B." it was hard not to feel pulled over to the dark side yourself.
