Greg Fidelman first worked with Metallica as engineer on the 2008 album Death Magnetic – a result of his long association with that album’s producer Rick Rubin.
Since the late 90s, Greg has served as engineer on numerous albums produced by Rubin, including System Of A Down’s self-tilted debut, the Red Hot Chili Peppers’ Californication, the posthumous Johnny Cash release American V: A Hundred Highways and Black Sabbath’s final album 13.
