A couple weeks ago Metallica surprised fans at the Orion Music And More Festival by doing a surprise performance of their classic Kill Em' All album. They were on the schedule as Dehaan(After actor Dean Dehaan who stars in their upcoming film, Metallica: Through The Never) to keep it on the down low. The first video, from MetallicaTV, shows some backstage rehearsal and some pro shot footage of the performance. The second video is a compilation of various fan shot material put together by MilanicaChannel and the audio is quite good. Turn it up loud!
