The show at Benaroya Hall saw Pearl Jam guitarist Mike McCready play three songs with the Symphony - under the direction of conductor Ludovic Morlot.

Commissioned by the Symphony, the songs included French composer Yann Robin's "Ashes", a piece inspired by Nirvana; "Beyond Much Difference" by Angelique Poteat and inspired by Pearl Jam; and, "Waking The Horizon", a piece conceived by McCready.

The Pearl Jam guitarist and the Symphony were then joined in the second half of the evening by bassist Duff McKagan, drummer Barrett Martin, Soundgarden vocalist Chris Cornell and Pearl Jam's Stone Gossard, Jeff Ament and Matt Cameron for a tribute to Mad Season, the 1990s Seattle supergroup made up of members from Alice In Chains, Pearl Jam and Screaming Trees.

The Sonic Evolution performance also included covers of two songs by Seattle supergroup Temple Of The Dog, "Call Me A Dog" and "Reach Down."

Mad Season released one album, "Above", in 1995 before going on permanent hiatus the following year due to the conflicting schedules of the group's members; Alice In Chains vocalist Layne Staley later died of a drug overdose in 2002.
