See Rob Zombie Joined by Lacuna Coil's Cristina Scabbia for Ripping "Am I Evil?" Cover

In 2006, Lacuna Coil opened for Rob Zombie on a six-week U.S. tour and the Italian metal band's frontwoman Cristina Scabbia and Mr. Zombie were fast friends. "We all know how much Rob influenced the scene and how great his live shows are," Scabbia enthused at the time; that live show got even better eight year later when the Lacuna Coil singer made a surprise appearance with Zombie during his Friday, June 27th show at Alcatraz in Milan, Italy. Even better yet, rather than just join the horror rocker for one of his solo or White Zombie hits, Scabbia took the stage to perform a cover duet of the Diamond Head classic "Am I Evil?" — which was, of course, popularized by a little band called Metallica. Fan-filmed video footage of her appearance can be seen above.
