"For the most part as much as I’ve enjoyed it, it’s just not been as much fun. It’s not been as rewarding."
- The Edge on doing work outside of U2, 2015
Starting life as two seperate demos, 'Ultra Violet' and '69', later evolving into 'Lady With The Spinning Head', The Edge improvised a riff that the rest of the band worked with. With said riff, 'One' was born, ultimately changing the outlook of the sessions and more importantly, keeping the band together.
