Well the Radiohead concert kind of blew anyways, it was way oversold and I was 500 feet back. And some guy was standing right in front of me so I couldn't see. So that made the decision a lot easier.
I have a rule about this: If it's a band that everybody has heard of, their concerts are no longer worth attending.
As much as I enjoy Radiohead, it would never cross my mind to go to their concert. Best show I've ever seen was the Flaming Lips about ten years ago, maybe longer, in a crappy concert hall in Houston called The Abyss (held about 900 people, but only about 400 were at that show...I paid $12 to get in and thought it was a bit steep). But, even though I have exceedingly fond memories of that show, I would not go see the Lips perform today. It'd just be a letdown.
I saw the Lips 3 years ago and had a blast, one of the best shows I've ever been to. There's an art to entertaining a small crowd, and one to entertaining a large one. My guess is that the Flaming Lips are masters at both.
Love your buddhist saying :D
