Fans in Greece got one heck of a treat last night (July 1st) when Phillip Anselmo jumped up on stage with Slayer to perform the classic Pantera song 'F-ing Hostile'. Watch this shredding performance and see if you can keep from tearing stuff up around you.

The show had some of the biggest hardcore metal bands like Slayer, Down, Napalm Death and more. During Slayer's set, Phil, who celebrated his birthday the day before, jumped up on stage and performed, not just any Pantera song, but one of the anthems that us hardcore Pantera fans know and love.
