Interesting bass, especially coming on the heels of his wacky Warwick. Not my style, but that's okay.
As for his playing, he is the perfect bass player for U2. Wooten, Jaco, Clarke, Bootsy, Graham, Entwistle, Squire, Bruce, who would create better U2 bass lines than Adam Clayton? None of the above, nor anyone else. Bass playing, like everything else, is meaningless without context, and for his context, Clayton is better than anyone else in the world.
Or would "News Year's Day" be better with a snaky 6-string fretless line full of ghost notes, false harmonics, diminshed chords, and a scrunchy around the nut? Ha!
