The 70,000 Tons of Metal cruise was already heavier than a slab of granite, but the floating metal fest just thumbed the scale even more. While aboard the ship -- which sets sail from Miami and float all the way to Cozumel, Mexico on Jan. 24 -- Bay Area thrashers Testament will perform their 1987 debut, 'The Legacy,' in its entirety.

But that's not all. At the second show aboard the cruise, they'll perform all of 1988's 'The New Order.' If you want more info on the 70,000 Tons of Metal cruise, visit their official website.
