Speaking to Classic Rock in 2015 for his fifth and final solo album, Higher Truth, the late Chris Cornell spoke with the equanimity of one who had seen it all and done most of it. As frontman with Soundgarden he was a pivotal cog in the musical revolution that cleared shop at the start of the 1990s, and later joined forces with the musical nucleus of Rage Against The Machine to form Audioslave. He died in 2017.
