U2’s best songs were written during these years—roughly from 1986, when they began recording “The Joshua Tree,” to 1997, the year “Pop” (which is actually very good) was released. But there was a problem: the songs depended for their power on the dramatization of Bono’s ambivalence about God.

U2 have continued to write songs of doubt (“Wake Up Dead Man,” off “Pop,” is especially good). But they are no longer wild, ludic, and unhinged in the way they talk about God. There used to be something improvisational and risky about their spirituality—it seemed as though it might go off the rails, veering into anger or despair. Now, for the most part, they focus on a positive message, expressed directly and without ambiguity. The band’s live shows have a liturgical feel: Bono, who regularly interpolates hymns and bits of Scripture into his live performances, leads the congregation with confidence.
