Metallica The metal men of Metallica will perform headlining sets at the U.K.'s Reading and Leeds festivals this weekend, and they’re going all out. According to Dick Tee, head of production for the main stage at Reading, attendees are in for a treat—a heavy one.

"It’s going to be mind-blowing," Tee told KERRANG! “Currently, we’re looking at something like 400m2 (400 square meters) of LED onstage—at least 100% more than any other act—so it’s a phenomenal visual sight."

The guys are bringing out lasers and pyrotechnics, to boot. "Within that they’ve got stage risers for the band to run up and down on, play on, and to accommodate some special guests you’ll find out about," Tee said.

Tee added he’s preparing for 18 trucks of equipment for Metallica.

"I spent 20 years as Head of Production at Glastonbury and worked most of the major festivals, and without a doubt this is probably the largest individual artist production I’ve ever dealt with," he said.

The Reading and Leeds Festivals will take place next weekend, and Metallica will add a metal flavor to the lineups, which are heavy on alternative acts. Mumford and Sons, Bastille, alt-J, All Time Low, Panic at the Disco and New Found Glory will perform at Reading on Friday and Leeds on Saturday. Metallica, Royal Blood, Catfish and the Bottlemen and Wolf Alice will play Reading on Saturday and Leeds on Sunday. The Gaslight Anthem, the Libertines, Against Me! and AWOLNATION will appear at Reading on Sunday and Leeds on Friday.
