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

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 on for a long time as the musicians were constantly fighting with each other. Kirk Hammett replaced Mustaine in 1983. ⁵⁾
