The gloriously chaotic career of Black Sabbath stands as testament to the indestructibility of British rock at its most extreme. In the world of heavy metal, no other band has lived life to the fullest, stared death in the face so many times, battled addiction, warred within themselves and still emerged, unbowed with as much bloody-minded persistence as Black Sabbath. Ozzy, Tony, Geezer, and Bill have survived against almost impossible odds, always making one more comeback than whatever the latest tally of disbandment's might be, and always celebrating it with yet another thunderous album. Joel McIver has conducted dozens of interviews with the musicians and those within the music industry who witnessed the roller-coaster rife of the band, as well as many other Sabbath musicians who have come and gone over the years.
