In the midst of the '90s, the grunge rock supergroup Mad Season emerged, led by Alice in Chains' Layne Staley with Pearl Jam's Mike McCready, Screaming Trees' Barrett Martin and the Walkabouts' John Baker Saunders completing the lineup. The band released one album, 'Above,' and were working on a second disc of music that was never finished before both Saunders and Staley passed away. However, just last year McCready and Martin decided to revisit their Mad Season work and see if they could complete what was started.
After recent word that a new album of previously unreleased Mad Season material is in the works, the band’s drummer Barrett Martin has revealed that singer Mark Lanegan (Screaming Trees, Queens of the Stone Age) will be contributing vocals to the effort. The band’s original vocalist, Layne Staley (Alice in Chains), died in 2002.
