Joel McIver (born 1971) is a British author. The best-known of his 21 books to date is the bestselling Justice For All: The Truth About Metallica, first published in 2004 and selling close to 50,000 copies in nine languages since then. McIver's other works include biographies of Black Sabbath, Slayer, Ice Cube and Queens Of The Stone Age. His writing also appears in many newspapers and magazines, including The Guardian, Classic Rock and Rolling Stone, and he is a regular guest on music-related BBC and commercial radio. In the introduction to a 2009 collection of rock writing, McIver was described as "probably the top [rock] scribe in the world", and in a book review in April 2012, Classic Rock magazine labelled McIver "by some distance Britain's most prolific hard rock/metal author".

¿¿In the world of heavy metal, no other band have lived life to the fullest, stared death in the face so many times, battled addiction, warred within themselves and still emerged, unscathed, unbowed with as much bloody-minded persistence as Black Sabbath. Joel McIver has conducted dozens of interviews with the musicians and those within the industry who witnessed the rollercoaster ride of the band, as well as many other Sabbath musicians who have been and gone over the years. This is the ultimate guide to the Black Sabbath legend.
This latest edition of Joel McIver's book, which has been translated into several languages, covers the late-career activities of Sabbath in detail, with new interviews, analyses of the music and speculation about the band members' futures.
