Besides Lollapalooza, the reunited Soundgarden has only performed small club shows with only a few days notice given to the fans. So it seems like no surprise that the grunge pioneers played a “secret” show Monday night (September 27) at Activision’s launch event for Guitar Hero: Warriors of Rock at the Paramount Studios back-lot in Los Angeles, California. The only difference is that it was so secretive that most people didn’t know about it till afterwards.

Soundgarden’s eight song set at the launch event is a continuation of their unique partnership with the new Guitar Hero game. As previously reported, the first one million copies of Guitar Hero: Warriors of Rock will actually feature a physical copy of the band’s new greatest hits album Telephantasm.

Apparently the set was transformed into a replica of now-defunct venue CBGB, but unless they went out of their way to make the bathrooms extra gross and had the mens room toilet on a throne with no door, it wasn’t completely authentic. Here’s some footage (courtesy of Christy Borgman) of the band performing “Spoonman” above and “Rusty Cage” after the jump, along with the set list of the night.
