STONE SOUR performed at the Rock In Rio festival in Rio De Janeiro, Brazil on September 24th, and pro shot footage of their entire set is now online. Check it out below.

As previously reported, ex-DREAM THEATER drummer Mike Portnoy was tapped to fill in for Roy Mayorga for the gig, as Mayorga opted to stay home for the birth of his first daughter.

Portnoy issued the following statement: "It's my honor and pleasure to be able to help out my good friends in Stone Sour and my brother Roy in their time of need. It's also an unexpected treat for me to get another visit with some of the greatest fans in the world down in Brazil."В В
