On August 10, 1991, Metallica performed at Gentofte Stadium in Copenhagen, Denmark, as part of the Monsters of Rock festival, which featured other notable acts such as AC/DC and Queensrÿche. At this point in their career, Metallica had just released their critically acclaimed self-titled album, commonly known as "The Black Album," less than a month earlier on August 12, 1991. This album marked a pivotal moment for the band, as it showcased a more polished sound and included hit singles like "Enter Sandman" and "The Unforgiven." The live recording captures Metallica during a transformative phase, where they were on the brink of mainstream success and solidifying their status as one of the giants of heavy metal. The Monsters of Rock tour was a significant event, being among their first major tours supporting "The Black Album" and marking Metallica's expansion into larger arenas and international prominence.
