"The last two records were very personal, with a kind of three piece at their heart, the primary colours of rock - bass, guitars and drum. But what we’re about now is of the same order as the transition that took us from The Joshua Tree to Achtung Baby."
- Bono, September 2008
The guitar riff in the beginning of the song 'Is That All?' is from the song Cry, which can be heard at the beginning of many live versions of 'The Electric Co.'.
