The Joshua Tree is the fifth studio album by rock band U2. It was produced by Daniel Lanois and Brian Eno, and was released on 9 March 1987 by Island Records. In contrast to the ambient experimentation of their 1984 release The Unforgettable Fire, on The Joshua Tree U2 aimed for a harder-hitting sound within the limitation of conventional song structures. The album is influenced by American and Irish roots music, and depicts the band's love–hate relationship with the United States, with socially and politically conscious lyrics embellished with spiritual imagery. Rolling Stone magazine ranked the album at number 27 on their 2012 list of "The 500 Greatest Albums of All Time", calling it "an album that turns spiritual quests and political struggles into uplifting stadium singalongs".
