Metallica drummer Lars Ulrich said the bands, which also include Slayer, Megadeth and Anthrax, have their eyes on a few more American dates. "We are looking to book something on the East Coast because of the success of this – it should hopefully come together in a week or two," Ulrich told RollingStone.com. "Maybe we'll do somewhere in the Midwest and South, too."
Although it looks like the Big Four are trying to cover all regions of the U.S., Ulrich said that metal fans shouldn't expect a full-blown American tour. "Still, I don't think it will turn into a 40-date arena tour; that would make it less special. I like the fact that there's an element of chaos to the whole thing. It shouldn't be sterile, streamlined and perfect: it needs an edgy underbelly to remain authentic."
