Rockers Chris Cornell and Duff Mckagan are joining newly reunited grunge supergroup Mad Season for a special concert.

The Seattle, Washington-based band only released one album, Above, in 1995, and the remaining members are coming together to mark its 20th anniversary for a special performance in their hometown next year (15).

The gig is part of the Seattle Symphony's Sonic Evolution series, which pays tribute to the city's musical past. For the second half of the evening, Original Mad Season members, Pearl Jam guitarist Mike MCCready and Screaming Trees drummer Barrett Martin will take to the stage with Soundgarden frontman Cornell and former Guns N' Roses bassist MCKagan.

The two will fill in for Alice in Chains singer Layne Staley, who died in 2002 following battles with addiction, and Walkabouts bassist John Baker Saunders, who died of a heroin overdose in 1999.

The new iteration of Mad Season will be joined by the symphony and members of Seattle's Vocalpoint! ensemble for specially arranged versions of the band's songs, such as River of Deceit, I Don't Know Anything and Long Gone Day.

Mad Season's Sonic Evolution series will take place on 30 January (15).
