Since its inception, metal has been deeply entwined in the world of both fantasy and horror. The almost-unanimous pick for the genre’s first album, Black Sabbath’s self-titled debut, instantly separated themselves from other bands at the time with their lyrics about unintelligible and dark figures in the night, wizardry, and possibly rock’s first true tip of the hat to the genius author H.P. Lovecraft. With the title of the album’s third track, “Behind the Wall of Sleep,” Black Sabbath not only revolutionized heavy music from a sonic standpoint, but lyrically as well. Bassist/lyricist Geezer Butler’s fascination with black magic and campy horror flicks in the early years of the band could certainly be looked upon as the genesis from which the Lovecraft obsession in metal truly began.
