Released in August 1991, "Metallica" features some of Metallica's most popular songs, including "Enter Sandman", "The Unforgiven", "Nothing Else Matters", "Wherever I May Roam" and "Sad but True". It spent four consecutive weeks at No. 1 on The Billboard 200 chart and is the band's best-selling album to date, with over 15 million copies sold in the United States and over 22 million copies worldwide. It's also one of the best-selling heavy metal albums of all time.
The album cover features only the band's logo and a coiled snake (derived from the Gadsden flag). The motto of the Gadsden flag, "Don't Tread on Me", is also the title of a song featured on the album.
"Metallica" DVD-Audio 5.1 mix was released in 2004 through Elektra Records.
