This week, on (Untitled), Ezra and Uma celebrate U2's deeply conflicted look at America on its thirtieth birthday. The Joshua Tree was an album made by four outsiders both in love and enraged with the place, by four outsiders who were inspired by the country’s theoretical potential but also saw what its foreign policy wrought in South America and Africa, by four outsiders who grew to understand that the same vast expanses of the United States that one might characterize as the Promised Land also sheltered brutality and violence in so many of its corners.
