On January 30, 2015, surviving Mad Season members Mike McCready and Barrett Martin performed selections from the band's repertoire at the Seattle Symphony's Sonic Evolution concert, with conductor Ludovic Morlot and guest artists including Soundgarden's Chris Cornell (filling in for the late Layne Staley), Pearl Jam drummer Matt Cameron and Guns N Roses bassist Duff McKagan (filling in for the late John Baker Saunders).

The Mad Season performance also included guests Jeff Angell, Kim Virant, Sean Kinney (Alice In Chains), Skerik, and Tim Dijulio.
The night also included an appearances from Jeff Ament and Stone Gossard who alongside Cornell, McCready, and Cameron, performed songs as Temple Of The Dog.
This event was the result of a year-long artistic collaboration between Mike McCready and Seattle Symphony Music Director Ludovic Morlot. Proceeds from the album sales will benefit the Seattle Symphony and the Vitalogy Foundation.
