In case you are wondering why I named the post "AchtungBB" it is from U2 classic 1991 album "Achtung Baby" This was a album with a ridiculous name, but a very serious message. I'd say this is the best U2 album ever.
GO back to 1991. U2 was still recovering from the criticism of Rattle and Hum. They were seen as too "self rightous". The band that made "the Joshua Tree" at a time of hair metal was now jamming with BB King. There's nothing wrong with that, but it's not forging new sounds which the band is known for doing.
Then they reinvent themselves as cyber punks and launch Zoo TV, a assult on the senses with pop culture and media. If they were going to be seen as self rightous, why not indulge in it? However the music would speak for itself-exploring the flip side of relationships in a time of madness, yet still finding beauty.
