"The spirit of rock & roll is always about innovation and energy, fucking with the technology that was around. In the early days that were just this little printed circuits they overloaded and then you got distorted guitar and amplified instruments. It’s just a different kind of technology now, but I think it’s the same spirit. Our version of rock & roll is reflected in the song MOFO. That’s rock & roll."
- Bono, 1997
