Photos: U2 rehearse for their world tour

U2 prepare to conquer the world yet again

About to embark on a tour that will span five months and more than 30 cities in a third as many countries, Irish rock titans U2 recently got in a quick rehearsal at Barcelona’s Camp Nou stadium (pictured). The storied quartet, whose hits include “With or Without You,” “One,” “Sweetest Thing” and the recent “Get on Your Boots,” has dubbed this their 360-Degree Tour as it sports a massive rotating stage. It’s the tallest setup ever used on a tour of this size, and reportedly requires 120 trucks to haul it around. But don’t worry—the band’s buying carbon offset credits to cover the environmental side. Let’s hear it for responsible rock!
