Not just the harmonies, but the vocals in general are absolutely the star on this album. Too many highlights to mention on their own.
Bono has remembered that there’s more to him than just screaming, and remembered in spectacular fashion. His vocals on Bomb were a massive let down, definitely one of the reasons why the album was so poor to me. But from NLOTH, to MoS to Breathe to Cedars, it’s a full display. Small things too. There are loads of great moments where there’s just a little double track in just the right spot, or a Bono or Edge falsetto quietly off somewhere in the headphones-only background. Then of course there are the up front, all in harmonies. I agree that the MoS chorus on its own would be a let down, but with that harmony it’s pure heaven. NLOTH and of course Unknown Caller as well.
There’s something really great vocally on almost every track.
