S&M2 is a live album by American heavy metal band Metallica and the San Francisco Symphony. The album is a follow-up to S&M, a live collaborative album released in 1999. Like S&M, the album was recorded during a live performance in San Francisco at the Chase Center in 2019. The performance was also filmed and released theatrically on October 9, 2019

On April 21–22, 1999, Metallica, in collaboration with the San Francisco Symphony and Michael Kamen, recorded and filmed a concert at the Berkeley Community Theater. The performance was released as a film and a live album in November 1999.

In March 2019, Metallica announced the S&M2 concert. The concert, which was similarly performed in collaboration with the San Francisco Symphony, was planned in celebration of the 20th anniversary of S&M. The concert was recorded and filmed at the Chase Center in San Francisco on September 6 and September 8, 2019 with Edwin Outwater and Michael Tilson Thomas conducting the symphony orchestra. The concert also marked the grand opening of the Chase Center. Filming was directed by Wayne Isham, who also directed S&M.

The film was released in theaters on October 9, 2019. The film earned over $1.2 million at the North American box office, and totaled $5.5 million internationally, making it the highest-grossing rock cinema event ever.^[11] As a result, the film was shown theatrically for a second time on October 30, 2019.

The live album was released on August 28, 2020. The film was released on Blu-ray the same day. The Blu-ray release includes a new revised version of the film edited by the band with remixed and remastered audio.
