Metallica will mark the 20th anniversary of their ‘S&M‘ concerts this year with a special performance in September. The band have been booked to once again play with the San Francisco Symphony Orchestra as part of the grand opening celebration of the Chase Center in San Francisco, CA on Friday, September 06th. The announcement was made earlier today (March 18th) and it was revealed that conductor Michael Tilson Thomas will be leading a portion of the show. You can watch the announcement ceremony here. Ticketing details for the show, which is being billed as ‘S&M²‘, can be found over at metallica.com.

The original ‘S&M‘ performances took place at the Berkeley Community Theatre in Berkeley, CA back in April of 1999. The live album release of those shows went on to go 5x multi-platinum in the United States, while the DVD/VHS release went on to go 6x multi-platinum.
