If you could see it then you'd understand

Should a concert contain note-perfect performances of an artist's best-known tracks, or should they try variations to breathe new energy and passion into the songs? I just came back from a Coldplay show, and I don't know the answer.

It's good to be able to sing along, but the rocked-out "Clocks" was much more rocking than the other tunes, which were replicas of the album versions--to the point where Chris Martin started over on two songs after messing up. At least it was live, but it's ok to miss a note or fiddle with the phrasing. Else it's just a CD listening party with a fancy light show.
