This is a thing:
Three years have passed since the last U2 world tour but now, just when you thought it was safe to go back in a stadium, two more may be coming at once. Despite the uncertain reaction to them delivering their new album onto almost every iPhone on the planet, the band’s belief that there is an unquenchable thirst for their music seemingly remains.
Bass player and noted spoon collector Adam Clayton recently spoke to Rolling Stone about their forthcoming live plans. "There is talk of doing two different kinds of shows,” he said. “One night would be a kind of loud, explosive rock’n’roll kind of event and then the other night’s show take the acoustic arrangements of some of the songs, and kind of present those songs in a much more intimate way. But we don’t really know how that’s going to sound and look."
You're not going to run out of people who will pay to see U2. It might be hard to sell records, but nobody's going to miss the nostalgia tour.
