St. Anger was released on June 5, 2003 through Elektra Records. Not only was it the band's first album of the 21st century, but it was the band's last album released through Elektra, thus marking the end of the longest timespan between studio albums from Metallica, with nearly six years between the release of ReLoad and this album. St. Anger was originally intended for release on June 10, 2003, but was released five days earlier due to concerns over unlicensed distribution through peer-to-peer file sharing networks. The album marks the final collaboration between Metallica and producer Bob Rock, whose relationship began with the band's fifth studio album, 1991's Metallica.
