St. Anger is the eighth studio album by American heavy metal band Metallica, released on June 5, 2003, through Elektra Records in the United States and Vertigo Records elsewhere. It was the last Metallica album released through Elektra and the final collaboration between Metallica and longtime producer Bob Rock, with whom the band had worked since 1990. This is also Metallica's only album without an official bassist, as Jason Newsted left the band prior to the recording sessions. Rock played in Newsted's place, while Robert Trujillo joined the band following its completion. Although he does not play on the album, Trujillo is listed as a member in the liner notes and appears in photos with the band in the album's booklet.
