Unlike many of their contemporaries, they were able to sustain such popularity in the '90s by reinventing themselves as a postmodern, self-consciously ironic, dance-inflected pop/rock act, owing equally to the experimentalism of late-'70s Bowie and '90s electronic dance and techno. By 1987, U2's following had grown large enough to propel them to the level of international superstardom with the release of The Joshua Tree. It's no accident that footage of Bono parading with a white flag with "Sunday Bloody Sunday" blaring in the background became the defining moment of U2's early career - there rarely was a band that believed so deeply in rock's potential for revolution as U2, and there rarely was a band whose members didn't care if they appeared foolish in the process.ĭuring the course of the early '80s, the group quickly built up a dedicated following through constant touring and a string of acclaimed records.

Through a combination of zealous righteousness and post-punk experimentalism, U2 became one of the most popular rock & roll bands in the world - equally known for their sweeping sound as for their grandiose statements about politics and religion.
