System of Down just need to get back and make an album already. They’ve been playing around the world lately, and have been killing it, even though it’s been a decade since they released an album. Playing at Rock in Rio, they brought out Deftones frontman Chino Moreno for the closing song, “Toxicity.” Chino does a pretty good job of channeling Serj Tankian, and the two sound great together. The whole set is in the above video. Chino comes out at about 1:23, but the whole concert is pretty great. What’s even better is that the band (minus Serj), played a hotel bar for 80 people after the shot, according to this short Instagram video from manager Dave Benveniste.
