Stay tuned later this week for our microsite dedicated to the design and technical components of the U2 360° tour, complete with blogs, interviews, video, photos, and more. Our own David Johnson was there for rehearsals. He and others will chime in over the next several months as the tour kicks off and progresses. In the meantime, below is a sneak preview of an interview with show director/designer Willie Williams, discussing the origins of the idea for the stage.
