Two grunge supergroups reunited in their home base of Seattle last night for a special concert called Sonic Evolution. Mad Season performed for the first time in 20 years with a lineup consisting of Soundgarden’s Chris Cornell, Pearl Jam’s Mike McCready, Guns ‘N Roses’ Duff McKagan, Barrett Martin, and the Seattle Symphony. Cornell and McKagan replaced late musicians Layne Staley and John Baker, who were originally on vocals and bass respectively. They played “River Of Deceit,” “I Don’t Know Anything,” and “Long Gone Day.” Cornell also joined Pearl Jam’s Jeff Ament, Stone Gossard, and Matt Cameron for a reunion of their one-off project Temple Of The Dog (without Eddie Vedder) and performed two tracks: “Call Me A Dog” and “Reach Down.” The last time they reunited was for a Bridge School Benefit last year. Watch all of the performances below.
