lo-American metal band Tool explores not only their uncompromising music but also their unsettling, self-made image based on mythological symbols and arcane theories.The quartet of master musicians - Maynard James Keenan, Danny Carey, Justin Chancellor and Adam Jones - emerged from the club scene in Los Angeles in 1990 alongside their friends Rage Against the Machine, grabbing the concept of heavy music and then completely redefining it.With a sixties-style commitment to art and agit-prop, they have now attained a level of artistic complexity and depth which makes their enduring success a miracle in today's culture of bland, corporate entertainment. Author Joel McIver leaves no detail omitted as he delves into the mystery behind Tool's music.
