Deane Galbraith, author of the fascinating "Fallen Angels" paper in Exploring U2, writes to say that he has a publication on U2 included in a new book out on theology and rock music, The Counter-Narratives of Radical Theology and Popular Music: Songs of Fear and Trembling (Palgrave Macmillan, 2014.) It's edited by Mike Grimshaw, and the U2 chapter is "Meeting God in the Sound: The Seductive Dimension of U2's Future Hymns." In the article, Dean employs Jean Baudrillard's distinction between the production of meaning and the seductive capacity of texts, in order to "examine the role played by U2’s emphasis on the formal, mystical, and experiential aspects of their music, and how that emphasis coincides with a religious trend which since at least the 1960s can be located throughout the arts, popular music, and—in a perhaps surprising association—charismatic evangelical Christianity." The chapter focuses on No Line On The Horizon and the U2 360 tour, and includes detailed discussions of "White as Snow" and "Unknown Caller." I haven't had a chance to look it over, but I've read enough of Deane's work that I expect it to be good!
