I have seen a few Beatles tribute bands and a phenominal Pink Floyd tribute band complete with orchestra perform many favorites including the entire Dark Side of the Moon.

My problem with tribute bands is they try to recreate the vinyl album (are there any tribute bands that cover artists that never recorded on vinyl???) too closely.

In most cases, the original band, if they performed the same song, would take liberties and play much differently than the original recording. What would be cool is if the cover band took liberties, and updated the arrangement(s) as if this is how the original band would do this live - stretching the arrangement a bit more creatively. If I want to hear the original recording, I'll go listen to the original recording.
