To say this year's Gigantour has a kick ass lineup (Black Label Society, Device, Hellyeah, Newstead and headlined by Megadeth) would be an understatement.

However, this past Saturday night (July 13th), in Dallas Texas no less, Gigantour flew right past kick ass and landed on legendary!

Megadeth decided to sing the Thin Lizzy classic "Cold Sweat" but they needed a little help from some friends. So out comes Jason Newstead on bass, Vinnie Paul on drums, David Draiman on one mic with Dave Mustaine on another with Zakk Wylde on guitar...as if that wasn't enough they were then joined by none other than Slash!

I don't need to tell you what the possible ramifications are for showcasing that much talent under one roof much less on one stage at the same time but I'll say this...Dallas TX is damn sure lucky they didn't get blown off the map. Watch the video below...you'll see.
