Metallica guitarist Kirk Hammet joined Anthrax onstage at The Warfield Theatre in San Francisco, CA last night, October 23rd. Hammet did guest vocals on “I Am The Law” and later played guitar on an abridged cover of Metallica‘s “Whiplash“. Fan-filmed footage (with admittedly crappy audio) of that can be found below:
