Premise: U2 . Subsequent work such as their first UK number-one album , War ( 1983 ) , and the singles `` Sunday Bloody Sunday '' and `` Pride ( In the Name of Love ) '' helped establish U2 's reputation as a politically and socially conscious group . The group 's fifth album , The Joshua Tree ( 1987 ) , made them international superstars and was their greatest critical and commercial success . This experimentation continued through their ninth album , Pop ( 1997 ) , and the PopMart Tour , which were mixed successes .
Hypothesis: U2 made an album.
