Metallica emerged in the early 1980s as a key force in the heavy metal scene, pushing the boundaries of the genre with fast tempos, aggressive guitar riffs, and dark lyrics. Their third album, *Master of Puppets*, is widely considered one of the greatest metal records of all time. Although originally underground, they gained massive popularity in the ‘90s with a more polished sound, bringing metal into the mainstream. Known for their intensity on stage and off, the band faced internal conflicts, particularly around the time of their documentary *Some Kind of Monster*, which exposed tensions and personal struggles behind the music.
