The latest addition to Classic Albums tells the story behind the making of one of Heavy Metal's greatest achievements: "Paranoid" by Black Sabbath. Released in the autumn of 1970, the album is regarded by many as the finest Heavy Metal album of all time. The four original members: Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward talk us through the making of the album via interviews, demonstrations, archive videos and use of the original multi-track tapes.
