Bono's lyrics have been solid, his voice in parts even better than in the 90s.
Adam's playing has improved out of sight, he's mentioned in several interviews about taking lessons and his playing and even re-invention of old bass lines has been a real highlight on recent albums.
Larry is Larry, his drumming is solid.
At the risk of being labeled a heretic, since the early 2000s, in my opinion it's Edge who hasn't dragged his sound forward in any way or really challenged himself with his output. In terms of guitar parts, he released much the same song a few times (vertigo, get on your boots, volcano, no line on the horizon), reverted back to 'the Edge sound' at most opportunities, doesn't seem to have chased anything particularly new in terms of sounds and effects and has stagnated a little.
There were moments! The beautiful tone at the end of the Troubles is a standout, though sadly, ultimately amounted to nothing.
I love the Edge sound, 360ms delay through a vox has served him well, but of the 4 lads in the band I would like to call out Edge as the guy who has been dragging his heels creatively for the past 15 years, and who can lead the band out of it.
Really hope that when SOE comes around, we're calling it an 'Edge Album'...
Who needs to lift?
