I've been to plenty of gigs on 360, and I have to say that 2009 was the dud of them. Even though I absolutely love NLOTH to death, it's my 2nd favourite U2 album... it didn't work out well. In 2010 it was fun with the new songs, but the REAL change was the energy with the band. Bono's cocky "I'm a cyborg" new persona, having so much fun with the crowd, it was brilliant. I didn't really care about the setlist at all.
Then 2011 came and it was even better. And there, the setlist did make the impact. Zooropa, so much AB stuff, goddamn awesome. Plus the energy that was already around in 2010. It all added up, for me those shows were the best I've ever seen.
Granted I have not seen shows live pre 360, so I cannot judge what they were like. I do know that from the reviews of people here who've seen the shows, I'm pretty psyched for September!
