As you may have heard, U2 are going on tour this summer to celebrate the 30th anniversary of The Joshua Tree. Each show will be devoted to performing the album in full. This is the first time many of these songs have been performed, by U2, in years. Both Bono and The Edge feel the topics approached in The Joshua Tree have as much relevance today, as they did in 1987, and they're excited about performing The Joshua Tree for the audiences.
