WATCH: 3 Members of Audioslave Play 'Like A Stone' With Serj From System of a Down!

Thanks to Rockaholic Eric Wilhite for the tip on this one. Three quarters of Audioslave now play in the supergroup Prophets of Rage, a collective that also boasts members of Run DMC and Cypress Hill. Last weekend, they played Rock Im Park, a festival in Germany, where they recruited an old friend of their old friend Chris Cornell, to cover Audioslave's 'Like A Stone'. Serj Tankian did not disappoint. Check out the pro-shot footage:
