Metallica (my preferred heavy metal band) realeased Metallica (also known as The Black Album), the eponymously-titled fifth studio album of this American heavy metal band. It was released on August 12, 1991 through Elektra Records to critical acclaim.

Metallica produced six hit singles that are considered today among the band's best-known songs: "Enter Sandman", "Don't Tread on Me", "The Unforgiven", "Nothing Else Matters", "Wherever I May Roam", and "Sad but True".
