If you were cursing your geographical locale and luck last night (April 12) because you could not attend the third edition of Samson's 'Metal Masters' clinic, which is essentially a heavy metal all-star jam, then you're in luck. If you've got three hours, you can enjoy a stream of the entire event which took place at the famed Key Club on Hollywood's even more famed Sunset Strip.

Both Phil Anselmo of Pantera fame and Geezer Butler of Black Sabbath turned up as special guests, joining the previously confirmed likes of Kerry King and Dave Lombardo (of Slayer), Mike Portnoy (ex-Dream Theater), Frank Bello and Charlie Benante (of Anthrax) and David Ellefson (of Megadeth.) It was a "Who's Who" of metal, that's for sure. If you were there, you witnessed something authentic. If you weren't on site, well live vicariously and pretend you were by watching the full stream.

Anselmo performed 'Vulgar Display of Power' anthems 'A New Level,' 'Mouth for War' and 'Walk,' while the evening closed with a cover of Sabbath's 'Hole in the Sky,' featuring Anselmo on vocals and Butler on bass. It's not every day that you get to see that metallic spectacle!

A little slice of metal history was made last night. We encourage you to watch the whole thing, but if you don't have the time right now, you can skip straight to Anselmo's appearance at the 2 hour, 19 minute mark. Check it out below:
