U2’s classic album “The Joshua Tree” was released on March 9, 1987. The LP features several of the band’s signature tracks, including “Where the Streets Have No Name,” “I Still Haven’t Found What I’m Looking For” and “With or Without You.” The album, named after a desert plant found in the Southwestern U.S., was produced by Brian Eno and represented their fifth studio effort. It marked a change in the band’s writing style, as frontman Bono and guitarist The Edge started mapping complete songs and bringing them to the other members of the group. Previously, the band had written most of their songs during free-form jam sessions.“The Joshua Tree” eventually reached the top spot on the U.S. charts. U2 had seen two previous albums, “War” and “The Unforgettable Fire,” reach number one in the U.K., but “The Joshua Tree” marked their breakthrough in America. They grabbed the top spot from the Beastie Boys’ “Licensed To Ill” and held it for nine weeks. They eventually gave up the number one spot to Whitney Houston’s “Whitney.”
