System of a Down frontman Serj Tankian joined Prophets of Rage at Germany’s Rock im Park Festival to pay tribute to the late Chris Cornell with a cover of Audioslave’s “Like a Stone.” “We had this long chat, sitting next to each other,” Tankian told Rolling Stone of his last encounter with Cornell, adding that they discussed working on more films. As Cornell told Tankian, “‘I’m really excited. I’m doing this tour with Soundgarden. I’ve got these other ideas.’ He had plans, man.” Tankian added that Cornell was “one of those guys” that “tried to make everyone in the room feel comfortable with themselves. He was generous that way, with his emotions and time.” Cornell died on May 17 shortly after a performance in Detroit, Michigan. Copyright(c) 2017 RTTNews.com. All Rights Reserved
