This is one of my all time favorite jams. I first saw Primus in 1991 at "Day on the Haight". They started the set with this tune. As soon as they started, something went wrong with La Londe's gear. Les and Herb jammed the shit out of this riff for 15 minutes or so while La Londe got his issue sorted. As I type this, it seems like it would have been boring, but it was one of the coolest things I have ever heard.
