"Ironic then, that at this point in their career U2 have started imitating their imitators, from Coldplay and The Killers down through various dilutions of their rousing, uplifting sound to arrive at a mediocre mix of the ubiquitous “ohs-ohs” and manicured “rock” guitars.
Each band member sounds diminished as a result, The Edge fated to roll out the same glistening but now rather emasculated riff over and over again, Bono lacking his incision of old and Larry Mullen and Adam Clayton belying their power as a rhythm section. Even the feistier, funkier likes of Volcano sound highly processed. Arguably, this is what an excess of producers does for you. Songs Of Innocence credits five, including old mucker Flood and longtime engineer Declan Gaffney, plus OneRepublic’s Ryan Tedder and Adele’s producer Paul Epworth.
At least Danger Mouse brings some class to bear on Sleep Like A Baby Tonight, its electronic pulse and gorgeous, resonant, distorted guitar sounding something like new territory, while the swooning strings and Lykke Li’s guest vocals on The Troubles make for an elegant coda to a pedestrian effort. Let’s hope experience wins out over innocence."
