On September 25, the world was brought to its knees by Mastodon’s performance at Rock in Rio VI in Rio de Janeiro. These Titans shared the stage with Metallica, Rod Stewart, Elton John, Rihanna, Katy Perry, System of a Down, A-Ha, John Legend, Queens of The Stone Age, Alice Cooper and so many more living legends at one of the worlds largest music festivals. From the first note the crowd starts a rumble like a hungry hurricane coming to devour its victims. 30 seconds into the show the crowd has lost their minds and their bodies convulse with pleasure and pain. Watch for yourself and let your eyes feast on this mind bending experience.
