10 Albums That Changed The Face Of Rock Music

10. Paranoid - Black Sabbath (1970)

Black Sabbath's self-titled debut introduced a new form of rock music to the world. Tommy Iommi masked his blues-inspired licks with plenty of distortion and a down-tuned guitar. Metal was born, and along with it, a foreboding dread would forever have a place on the fretboard.

Although that record opened up new realms of musical hell, it paled in comparison to the group's follow up release. If Black Sabbath birthed metal, then Paranoid crafted it into the beast it would become. The ominous doom and gloom of Sabbath's debut set the tone, but the group's follow up proved that doom and gloom could be tuneful. Epics like War Pigs, Iron Man and Paranoid were as catchy as they were heavy. And then there's Planet Caravan. It was blues-infused psychedelia, augmented by a hint of latin music, thanks to a subtle application of a conga drum.

One moment you're floating through ambient bliss, the next you're wrestling with the metal beast, Iron Man. Metal heads, grunge fans and alternative rockers, have this album to thank for generations of musicians tuning down their strings and turning up their amps.
