Who knew Kurt Cobain was a Metallica fan? Kirk Hammett spills the beans in this exclusive clip, not available on the DVD, from the documentary Get Thrashed: The Story of Thrash Metal, about how the poster child of grunge "loved Ride the Lightening and 'Whiplash.'"

Written and directed by Rick Ernst of MTV’s Headbangers Ball fame, the newly-released Get Thrashed, tells its story through more than 50 interviews with thrash metal’s most prominent figures, including members of Metallica, Megadeth, Anthrax, Slayer, Pantera, and more. Watch Kirk Hammett below.
