This past Saturday (May 18) marked the second anniversary of Chris Cornell’s passing.

At a set during Sonic Temple Music + Arts Festival in Columbus, OH on the 17th, Tom Morello and System of a Down’s Serj Tankian paid tribute to the late Cornell with a performance of Audioslave’s ‘Like A Stone’.

Following a Rage Against The Machine medley, Morello invited Tankian onstage which surprised and delighted fans. The crowd joined together and sang along with Tankian and cheered on Morello during his guitar solo.
