Metallica is set to celebrate its 40th anniversary in grand style.
The band is "taking over" San Francisco for four days coming up, December 16, 17,18 & 19.
Two nights at the Chase Center have already sold out.
But, fans can still get in on the fun with other events including a separate performance by the band Wedding Present, featuring Metallica guitarist Kirk Hammett and bassist Robert Trujillo.
There's also a Metallica Film Fest happening on December 18 plus pre-parties throughout the four days and even a Metallica Trivia Night.
