In April 1986, Metallica was riding high on the success of their groundbreaking album *Master of Puppets*, released just a year earlier and hailed as a classic in heavy metal. This live recording from the Joe Louis Arena in Detroit, during the *Damage, Inc.* tour, showcases not only the raw power and authenticity of Metallica's performance but also the band's evolution during a pivotal moment in their career. What’s particularly noteworthy about this concert is that it features tracks that were largely unreleased at the time, with only "Creeping Death," "Am I Evil?" and the title track "Damage, Inc." having made their way into the public arena before this performance. With Ozzy Osbourne as a supporting act, this show signified Metallica’s growing prominence in the world of rock, as they transitioned from the underground scene to becoming a headlining powerhouse. It’s fascinating to think about how they were just a few years away from changing the landscape of heavy metal forever. Isn’t it incredible how a single performance can capture such a dynamic moment in musical history?
