Ozzfest '99 was a helluva tour. Black Sabbath headlined the main stage that also boasted Rob Zombie, Deftones, Slayer, System of a Down and more, while the second stage featured up-and-comers like Static-X, Fear Factory and an itty bitty band from Iowa called Slipknot.
At one stop during this monumental trek across North America, System of a Down bassist Shavo Odadjian picked up a guitar and joined Wayne Static and Co. to help them perform "I'm With Stupid," a standout from their just-released 1999 record, Wisconsin Death Trip.
Although System were quite a bit bigger than Static-X at the time, the fact that Odajian was friends with them makes sense. Static-X's sound always drifted somewhere between conventional nu-metal, high-octane industrial and freaky-as-hell alt-metal that had a very similar energy to System's early stuff, so it was only natural that the two bands would get along.
For this performance, Odajian basically acted as he would on stage with his main band: head-banging, whipping around his braided beard and making bizarre faces while he hammered out the crushing rhythm parts. In this instance, Static was able to drop the rhythm guitar duties and just focus on his ferocious vocals, and the whole set had a fun, loose energy because of it.
