Two members of METALLICA's road crew caught fire during each of the first four Mexico concerts, as the two stagehands were seen struggling with a malfunctioning pyro launcher during "Enter Sandman" when both were suddenly engulfed in flame. As James Hetfield called for the band to stop playing, other crew members doused the men with fire extinguishers and took them off the stage in stretchers, with the band resuming its show a few minutes later.

A spokesperson for the promoter said the stunt was "all part of the show," and in fact METALLICA has staged this type of "accident" before during its 1997 tour, on which the show ended with the stage seemingly collapsing around the band as one crew member caught fire and another dangled upside down from the fallen lighting rig. The effect was caught on the band's "Cunning Stunts" DVD.

The show on July 28 marked the debut of a new 140-foot-by-50-foot stage that features "colossal components and striking visual elements spanning METALLICA's entire 30-year career," meaning that the "accident" stunt could be back for an encore.

At a press conference before the show, frontman James Hetfield said that the band was focused on "staying alive" while performing alongside the "dangerous elements" of the new production, with bassist Robert Trujillo adding, "Like James said, it's very dangerous — we've got stuff flying every which way."

A post in the "Tour Journal" section of METALLICA's official web site related that "shit really hit the fan (during 'Enter Sandman' with) loud bangs, random fireworks, falling towers, falling spot light guy, falling scaffolding, guy was caught on fire . . . then a complete blackout."

Following its Mexico City stand, METALLICA next plays the Outside Lands festival in San Francisco and then two shows in late August in Vancouver, which will be filmed for the band's upcoming 3D movie.
