I would love SOE to sound like the snippets we can hear in this video from The Edge :
I've just listened back to the "SOE Being Born Clip" and i love this raw, agressive sound !
I wish they'll go further in that direction!
Based on what little we've heard, the general direction of Edge in the last few albums (vertigo, GoYB, Miracle, Cedarwood Road), talk of SoE being aggressive and raw, and hell, even the wealth of distortion pedals we saw in that instagram post, it seems Edge is indeed very set on a sort of classic/hard rock guitar sound.
Not necessarily a bad thing, but I do suspect it's slightly incompatible with making a modern and/or successful 'hit' (I'm not overtly aware of what's topping the charts these days, but i feel 'rock' songs aren't as big as they were even 10 years ago). Unless they do something clever with the classic rock formula, I think that straightforward garage band rock sound could sound dated.
Having said that, I really like Edge's guitar work in the verses of The Best Thing - it's clearly a heavy, angry distorted guitar riff, but it contrasts so well with the lighter, dancey, upbeat club arrangement that the drums/bass/synths have. So perhaps a fusion of that more hard rock sound with something dancey fused with it could be a way for U2 to reinterpret/reintroduce rock, in contrast to say, Coldplay going full-EDM with the Chainsmokers.
