U2 and Nietzsche battle it out on the big screen?

The relatively new IVP Academic book Faith, Film and Philosophy: Big Ideas on the Big Screen has an essay by Douglas K. Blount from Southwestern Baptist Theological Seminary called "Rattle and Film: U2, Nietzsche, and Salvation in the Blues." It looks as if the author also presented a version of the paper at the Evangelical Theological Society meeting in Nov 2007. Kind of pleased by Blount's notion that for U2, "all roads to the Gospel lead first through the blues... gospel without blues leads to self-deception."
