Paranoid has been hailed as the greatest heavy metal album of all time. This was the album that distilled the essence of the doom-laded sound of Black Sabbath and burned the name into the minds of rock fans all over the planet. Featuring ultra-rare archive film of Black Sabbath in concert previously unreleased on DVD plus the reflections of Ozzy Osbourne, Geezer Butler, Tony Iommi, Neil Murray and Bobby Rondinelli alongside the views of a leading team of working musicians, musicologists and rock journalists, this is the definitive review of how the album was made and how the music has stood the test of time. Features rare archive performances of tracks Black Sabbath, N.I.B., War Pigs, Iron Man, Hand of Doom, Rat Salad, Fairies Wear Boots and Paranoid. Black Sabbath have been so influential in the development of heavy metal rock music as to be a defining force in the style. The group took the blues-rock sound of late-'60s acts like Cream, Blue Cheer, and Vanilla Fudge to its logical conclusion, slowing the tempo, accentuating the bass, and emphasizing screaming guitar solos and howled vocals full of lyrics expressing mental anguish and macabre fantasies. If their predecessors clearly came out of an electrified blues tradition, Black Sabbath took that tradition in a new direction, and in so doing helped give birth to a musical style that continued to attract millions of fans decades later.
