Thrash metal has always been a culture unto itself. It has its own movements (see San Francisco and Teutonic thrash for proof), its own fashion (snapbacks and patched-up denim) and even its own pantheon of gods: Metallica, Slayer, Megadeth and Anthrax. But, when members of this extreme metal cult look beyond their borders, things can get incredibly interesting. From legendary veterans to young guns, these are the best cover songs ever released by thrash metal artists.
