After the breakup of Soundgarden, Chris Cornell recorded an outstanding solo album that nobody bought. So instead, he pretended like that never happened and formed Audioslave.
Doesn't it drive you mad when an artist you love doesn't properly acknowledge their own work because it didn't get popular enough at the outset?
Listen to "Pillow of Your Bones"! It's one of many notable songs on that solo record: Euphoria Mourning. Those chord formations are bonkers! The drumming by Josh Freese is poised; his fills re-entering the song after the middle interlude are some of my favorite. Chris Cornell doesn't go totally out of his mind vocally, but his control is fantastic; he winds a soulful melody through some very challenging changes.
He should still be providing renditions every night to packed houses.
