My personal favorite U2 album, and seminal as far as production goes. Eno and Lanois helped U2 take the wall of sound to a whole new level. Some overlooked favorites include "Ultraviolet (Light My Way)" and "Acrobat".
I remember when there was a time I was so sick of hearing Scar Tissue, but it takes me back when I hear it now. And Around the World and of course Californication...
This was such a craze. I remember kids walking down the hall in their wide leg jeans singing Paranoid Android and Karma Police. We were so cool.
