A two-minute video "wrap-up" of this year's Knotfest, which was held last month at San Manuel Amphitheater And Festival Grounds in San Bernardino, California, can be seen below.
SLIPKNOT performed its 2001 album "Iowa" in its entirety at the two-day Ozzfest Meets Knotfest event, which took place September 24-25.
According to the San Bernardino County Sheriff's Department, about 37,000 people attended the event on September 24 (Ozzfest),and around 25,600 people attended the event on September 25 (Knotfest),with 3,470 campers on the festival grounds.
Saturday's Ozzfest lineup was headlined by BLACK SABBATH, while SLIPKNOT closed out Sunday's Knotfest bill.
Also on the Ozzfest portion of the weekend were DISTURBED, OPETH, BLACK LABEL SOCIETY and others, while the Knotfest lineup included SLAYER, TRIVIUM, ANTHRAX, SUICIDE SILENCE and many more.
Both days featured three stages, with one of them named after late MOTÖRHEAD frontman Lemmy Kilmister.
"Iowa" came out in August 2001 and followed up SLIPKNOT's double-platinum 1999 major label debut.
SLIPKNOT is playing the final shows of the world tour in support of its latest album, ".5: The Gray Chapter", which was released in October 2014.
