update: Citing inadequate crowd control, Limp Bizkit [ tickets ] has pulled out of Australia's Big Day Out festival. The band left the tour after a Friday night (1/26) performance in Sydney during which 30 people reportedly were injured and one young woman suffered a heart attack.

"We'd like to express tremendous sorrow over the injuries suffered by our fans during the Big Day Out concert," the band said in a written statement. "Concern for our fans' safety and well-being is our first priority, and to have people hurt during what is supposed to be an enjoyable and unifying experience affects us profoundly."

According to Australian press reports, the crowd at the Showgrounds in Sydney surged forward as Limp Bizkit, the final act of the all-day, multi-act show, performed at about 9:30 p.m. Attendance at the show was estimated to be about 55,000, and temperatures during the day were in the mid-90s.

The young woman who suffered the heart attack reportedly was passed unconscious over the top of the crowd to the side of the stage. She was admitted to a nearby hospital in critical condition. Others were treated for less serious ailments including heat exhaustion and back injuries, according the Australian Associated Press. After the crush, firefighters reportedly cooled the crowd with high-pressure hoses and passed out water.

Organizers issued a press release that blamed the problems on excessive heat and on an unusually volatile crowd.

"Several times during their performance, Limp Bizkit urged the audience to step back and assist fellow concert goers..., and promoters compliment the band's diligence in this," the statement said. "The organizers of the event would like to acknowledge the full co-operation of Limp Bizkit through this difficult situation and their commitment to the safety of their audience."

However, Limp Bizkit issued a press release accusing concert promoters--Creative Entertainment (Australia)--of ignoring the band's pleas for better crowd control. The band claims that it was forced to stop its performance during the first Big Day Out show on Jan. 19 in Auckland, N.Z., so that security could bring the crowd under control. In the wake of that performance, the band claims that frontman Fred Durst demanded heightened crowd-control measures, including a "T"-style barricade in front of the stage and additional security.

"We basically begged this guy to increase security measures and we were told he has been doing the event for 10 years and that he knows what he's doing and to leave him alone," Durst said in a statement.

Said band manager Jeff Kwatinetz: "Though we tried to explain that crowds are different from 10--or even 3--years ago, we were ultimately frustrated by his response. Any promoter who sticks his head in the ground and refuses to believe that audiences have changed is asking for a tragedy."

Organizers of Big Day Out, in a statement issued on the event's official website, argued that Limp Bizkit's proposed security changes weren't feasible. Promoters also claimed that the security staff was nearly doubled in the shows leading up to the Sydney event.

"The measures proposed by Limp Bizkit were substantial, untested, and radical changes to the existing structures and procedures in place for the show as understood by the Australian safety authorities, including the police and planning bodies," the statement read. "Additionally, the changes would have required substantial revisions of existing safety protocols and the promoters were unprepared to introduce these measures at short notice and with little preparation for security staff.

"Unfortunately the band performance was of sufficient intensity to provoke unprecedented and ferocious crowd activity in front of the stage."

Additional barriers and security staff will be added for the three remaining shows on the Big Day Out itinerary, which is scheduled to continue on Sunday (1/28) in Melbourne, according to tour organizers. Australian band Powderfinger will move into the headlining slot for the remainder of the tour.

"Given the tension between [Limp Bizkit] and [organizers] across a range of issues, the producers have expressed some relief at the departure of Limp Bizkit," organizers said.

Other bands on this year's Big Day Out bill include Coldplay, Rammstein, P.J. Harvey and You am I.
