Metallica (also referred to as The Black Album) is the fifth album by the American heavy metal band Metallica, released August 12, 1991 through Elektra Records. The album features songs that are considered today as Metallica's most known tracks, with songs such as "Enter Sandman", "The Unforgiven", "Nothing Else Matters" , "Wherever I May Roam" and "Sad but True". It is the second best-selling album of the SoundScan era.
The album cover features only the band's logo, angled against the upper left corner, and a coiled snake (derived from the Gadsden flag) on the bottom right corner, both in a dark shade of gray in order to be made out against the black background. The motto of the Gadsden flag, "Don't Tread on Me", is also the title of a song featured on the album.
