The Pulse of Radio reports: Although the breakout of swine flu that originated in Mexico has led numerous musical acts to cancel performances there, METALLICA is not backing down. According to a post at the website of AVENGED SEVENFOLD, who will open the shows, METALLICA has booked three concerts in Mexico City on June 4, June 6 and June 7. Although Mexico City is where the flu first surfaced, Mexican health secretary Jose Angel Cordova said on Thursday (April 30) that the number of cases seemed to be stabilizing, which means the crisis could be passed by the time METALLICA arrives next month.

Billboard.com reported on Thursday that dozens and dozens of concerts across Mexico were canceled or postponed, while premieres and press junkets for new movies like "X-Men Origins: Wolverine", "Star Trek" and "Terminator Salvation" were also either scrapped or in jeopardy.
