The ever-satisfying Heavy MTL festival, which takes place in Montreal, Canada, every summer, delivered yet again. The festival was packed with some of metal's biggest acts and displayed a particularly diverse lineup that appeals to all sorts of fans across the genre's vast spectrum. The billing ranged from Avenged Sevenfold and Godsmack, to Children of Bodom and At The Gates, to Mastodon and Finntroll, with a host of others gracing the stage including a special performance from Danzig with Doyle and Rob Zombie.

As if Danzig with Doyle wasn't enough of a treat for the fans in attendance, Rob Zombie also joined the stage to help perform the Misfits classic 'Vampira.' For those who were unable to attend Heavy MTL, there is footage of this once-in-a-lifetime event for all to see (watch above).

Rob Zombie's presence onstage adds energy to what is already the usually intense performance from Danzig, adding extra excitement to this event. The quality of the footage isn't professional, but if you crank your speakers loud enough (as if they would be anything but loud already) the audio quality becomes much more tolerable and distinguished.
