Just a general comment/observation on Adam's bass-playing... Early Adam is quite adventurous. You can see this, for example, on the "Under a Blood Red Sky" concert. Lots of slap, funk, even reggae. They kind of let him do what he want. After Adam began taking formal lessons later in his career, it seems this adventurous spirit was tempered (whether by the formal training or the rest of the band putting a lid on it, I do not know). I'm of the opinion that if "Gloria" was written today, his entire bass solo in the break would have disappeared. And that would be a shame.
He still has really great bass lines, but the experimentation and variation has lessened as he has become more proficient.
