U2 albums have long involved drawn-out sessions and an excess of material – a lot of it hears the light of day but enough from 2004's How To Dismantle An Atomic Bomb's sessions to birth a whole 10-track record; How To Re-Assemble An Atomic Bomb.
How To Dismantle… was very much a continuation of U2 leaning into the calling cards they'd rediscovered on 2000's All That You Can't Leave Behind – especially what Edge called his 'Coca-Cola' guitar sound. You know, chiming delay propelling big anthems.
