I saw Sound Garden open for Guns and Roses two nights at the Nutter Center, Fairborn Ohio. The Nutter Butter (as it's called) has horrible acoustics, and Christ Cornell sounded like shit first night. He was actually booed. This was one of Axl Rose's notorious late shows. Thankfully, me being security/usher I got paid to stand around.
Here we are many moons later, still blows my friggin' mind that Chris Cornell (Sound Garden) opened for Axl Rose (GnR).
