Lars Ulrich spoke to RollingStone.com concerning more Big 4 US shows:
"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 said. "Maybe we'll do somewhere in the Midwest and South, too. 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."
