"What I did was push the performance aspect very hard, often to the point of recklessness. I think that musical recklessness goes a long way on records. You don't hear enough of it."
- Daniel Lanois, on recording the Achtung Baby album
The song 'Numb' is about how The Edge felt when he split up with his wife. He felt like he couldn't do anything, he was useless. He felt numb.
