Bono Girl fan on stage '89

"We're at a point where production has gotten so slick that people don't trust it anymore... We were starting to lose trust in the conventional sound of rock & roll - the conventional sound of guitar ... those big reverb-laden drum sounds of the '80s or those big, beautiful, pristine vocal sounds with all this lush ambience and reverb. So we found ourselves searching for other sounds that had more life and more freshness." - The Edge, explaining the band's motivation for seeking a new sound with Achtung Baby
