Continuing the tradition of featuring heavier musical guests, NBC’s Late Night With Jimmy Fallon had none other than Anthrax perform on last night’s (September 7) show. The band played “The Devil You Know” for the first time live on the air. Then for a web exclusive, Anthrax tore into “Caught In A Mosh.” Though sadly no one actually broke into a mosh during the performance (missed opportunities, Jimmy, missed opportunities), it was obvious that the fans sitting behind the band were headbanging and having a damn good time.

You can check out footage of Anthrax performing “The Devil You Know” (as long as it lasts online) in the video above. The clip of Anthrax performing “Caught In A Mosh” posted online by NBC can be seen after the jump.
