This revised version of Walk On: The Spiritual Journey of U2 picks up where the first edition left off - amid the cathartic atmosphere of the post-9/11 Elevation tour that ushered in the aggressive spirituality of 2005's Vertigo tour. It explores the controversy surrounding the deep-rooted religious themes of the band's music and the outspokenness of their lead singer, Bono. Moreover, it is a spiritual companion to their albums, exposing the real meaning behind many of their songs and performances.
