The Joshua Tree/U2 (1987)
This U2's 5th album released in 1987 can be said to be their magnum opus, which led to the establishment of their world-wide popularity. It marked No.1 both in the American and the U.K. album charts, and won the Grammy Album of the Year Award. Two singles, 'With Or Without You' and 'I Still Haven't Found What I'm Looking For' too marked the No.1 in the U.S. chart. This album which is based on truly profound and sonorous style of music is a grand message album even with religious fragrance. They are always serious about the social problems as 'Bullet The Blue Sky' showing their protesting attitude toward America's intrusion into El Salvador and Nicaragua and 'Red Hill Mining Town' with strikes at a coal mine as its theme. This album pushed U2 up to a sort of deificated existance which is more than a mere rock band. Another important factor associated with this album is fablous guitar-plays by the Edge. His absolutely unique playing style effectively utilizing delay effects was completely established in this album although you could get a glimpse of such a style in the song called 'Pride (In The Name Of Love)' previously. Especially, his guitar works in the introduction section of 'Where The Streets Have No Name' are just magnificent. There are a bounch of guitarists who tend to be more technical or faster, however, the Edge was really going his way.
