The"S&M²"concerts featured METALLICA reuniting with San Francisco Symphony for the first time since the original"S&M²"performances in 1999 documented by the Grammy-winning live album"S&M"— plus the first-ever METALLICA/San Francisco Symphony renditions of songs written and released since those shows. Filmed over the two sold-out METALLICA shows that opened the Chase Center — the new 18,064-seat arena in San Francisco —"S&M²"captures more than two and a half hours of James Hetfield,Lars Ulrich,Kirk Hammett and Robert Trujillo joining forces with the nearly 80-strong San Francisco Symphony,with a special appearance by legendary conductor Michael Tilson Thomas.
