Metallica is an American heavy metal and thrash metal band founded in Los Angeles, California in October 1981 by James Hetfield and Lars Ulrich. Metallica is considered one of the most important and influential metal bands of the 1980s, the most profitable metal band in the 1990s and one of the most popular and outstanding heavy metal bands in history. Metallica is considered one of the “Big Four” of thrash metal. They are joined by Megadeth, Slayer and Anthrax. ¹⁾

Metallica's album Death Magnetic (2008) has been named the loudest ever by a mastering expert. It was mixed by Rick Rubin. ²⁾

St. Anger is Metallica's first and only album to not have guitar solos. This album is also notorious for its snare drum sound, which is often compared to playing on pots and pans. It was also recorded around the time when Metallica almost disbanded. Bob Rock was responsible for mixing this album and saving the band. ³⁾

Metallica was added to the Guinness Book of Records. It was the first band in history to play on seven continents in one calendar year. It happened in 2014. ⁴⁾

The official reason for Mustaine's expulsion from the band is that he was difficult to bear under the influence of alcohol and drugs. He got into a fight with James Hetfield, and it was the fight that led to his kicking out of the band. It had been heading this way for a long time, as the musicians were constantly fighting with each other. Kirk Hammett replaced Mustaine in 1983. ⁵⁾
