Description
Although rooted in the thrash metal genre, the album showcased the band’s musical growth and lyrical sophistication. Bassist Cliff Burton introduced the basics of music theory to the band and had more input in the songwriting. Beyond the fast tempos of its debut Kill ‘Em All, Metallica broadened its approach by employing acoustic guitars, extended instrumentals, and more complex harmonies.
The artwork, based on a concept by the band, depicts an electric chair being struck by lightning flowing from the band logo. The title was taken from a passage in Stephen King’s novel The Stand, in which a character uses the phrase to refer to execution by electric chair.
