For over 50 years, John Mayall has served as a pioneer of blues music, rightly earning him the title, "The Godfather of British Blues." In 2013, John signed with producer Eric Corne's label, Forty Below Records, and has since been experiencing a true artistic and career renaissance, including a Blues Hall of Fame induction in 2015. Joel McIver is a British author. The best-known of his books is the best-selling Justice For All: The Truth About Metallica, first published in 2004 and appearing in nine languages since then. McIver's other works include biographies of Black Sabbath, Slayer, Ice Cube and Queens Of The Stone Age, all published by Omnibus Press.
