Whew!
Well, I started this post and did not expect this big of a thread. When I read the interview with Mike McCready (regarding their setlist behaviour) I thought that it really made sense. A music group writes/rehearses/creates songs to record and to eventually perform live before an audience. Over the years, they put out several albums and become better and better performing live with a (hopefully) hefty back catalogue songs to offer their fans at concerts. Most people enjoy hearing a variety of songs with a good helping of "hits" (maybe not the same ones every time). To keep it fun for both the band and audience, most bands like to mix up their live offering so it doesn't get dull for anybody ("We like to keep the fans surprised, and we like to keep it fresh for ourselves, too.")
However, the fact that U2 has become the most popular band on the planet brings up some tough issues. Do they try and appease the greatest number of fans by playing an established set list that exposes the greatest number of fans to generally the same experience (thereby creating a singular/consistent global experience that pleases the majority)? Or do they offer up a greater variety of songs (while still throwing in the "hits") while risking the chance of alienating a larger portion of this global audience? Obviously, U2 has chosen the former. In a sense, this makes U2 no more than a circus/play where the same acts/dialogue are performed night after night. Perhaps U2 is now more a mix between music/performance art than a "rock and roll band".
U2 has admitted to being a corporation and sadly, this type of standardization philosophy fits (though the fact that they have behaved like this since the beginning throws this theory for a mild loop). Don't get me wrong, I am a huge fan (I saw them 5 times in the spring and will see them twice this fall)...but I'm beginning to appreciate my 2nd favorite band, Pearl Jam more and more (I'll be seeing them this fall as well). Also, I don't think I'll see as many multiple U2 shows on their next tour (if there is a next tour).
One thing I will grant U2 is the "religious" experience (perhaps only possible through massive repetition and perfection) some people have talked about. The thought of hearing "Streets" right now does not excite me at all...but if I were in a stadium hearing it right now in Europe, I know I would be stoked and totally into it . Taking this into account, I know I would be even MORE excited if I heard new songs on a regular basis (even over the course of 3-4 shows over 8 months). As powerful as the U2 live experience is with their static setlists...imagine how even more powerful it could be with variation. I'm sure Larry wouldn't mind skipping Sunday Bloody Sunday for at least a few nights.
Regardless, after reading this thread, I've begun looking at the U2 live experience in a different light. Basically, I'm more understanding as to why they do what they do...but still slightly bummed because it is the reality associated with being the "world's biggest band".
