When Max Cavalera split with Sepultura, the trailblazing Brazilian metal group he co-founded with his brother Igor, he called on many of his famous friends to help him get his new band, Soulfly, off the ground. Members of the Deftones, Fear Factory and Limp Bizkit all guested on the group's self-titled debut, and when it came time for the tribal metal crew to record a follow-up, Cavalera took the all-star cameos to another level. 2000's Primitive welcomed contributions from Deftones' Chino Moreno, Will Haven's Grady Avenell, Slayer's Tom Araya, John Lennon's son Sean and, of course, Slipknot's Corey Taylor.
Taylor's song "Jumpdafuckup" stands as the "hit" from Primitive, a irresistible rap-rock anthem that's dumb and fun and serves as a perfect time capsule from the nu-metal era. For all the cut's popularity, Taylor and Soulfly haven't played the song live together many times, but when they have, the crowds have gone wild. One such occasion was at Belgium's Graspop Metal Meeting in 2006. "Oh god, are you ready for some shit right now?!" Taylor roars by way of introduction, and the audience clearly was. See the madness above.
