7. Mad Season
Key Members: Mike McCready (Pearl Jam), Layne Staley (Alice In Chains), Barrett Martin (Screaming Trees) and John Baker Saunders (The Walkabouts)
Signature Songs: "River of Deceit," "I Don't Know Anything," "Long Gone Day"
Current Status: The Seattle supergroup had a very brief existence largely due to Staley's growing drug habit and Pearl Jam's busy touring and recording schedule. Saunders died of a drug overdose in 1999, and Staley followed three years later. In 2015, McCready and Martin got together with Chris Cornell and Duff McKagan to honor the group's music with a gig at Benaroya Hall in Seattle.
