Lip-synching, amendment of concert sound, miming, whatever you call it is *always* a rip-off. If you can't see (and hear) the musicians sweating and making mistakes, you are *not* listening to live music and you might as well have saved your cash and stayed at home to listen to the CD. In the creation of which perfect sound is expected and multi-tracking and digital massaging and all the other tricksy bits that sound engineers can get up to is acceptable IMHO.

And there are *far* too many Guests on this thread, so I suspect that whatever consensus may be emerging will be about as reliable as CW's sound in concert...
