Former Soundgarden frontman Chris Cornell and Alice In Chains guitarist Jerry Cantrell joined Pearl Jam onstage at Los Angeles’ Gibson Amphitheatre this past Tuesday (October 6). Cornell joined frontman Eddie Vedder for Hunger Strike, which transformed the band into Temple Of The Dog, the stars’ short-lived tribute band - they released just one album in 1991 - to deceased Mother Love Bone frontman Andrew Wood. Cantrell then closed the set with a guitar solo on Alive. See fan-shot footage below.Hunger StrikeAlive
