Regarding Sean Daly's Oct. 31 front-page article "In Concert, but Not Live": The electronic enhancement of concert performances has spread to the legitimate stage, where credit is now given for "sound design."

At a recent Broadway show, the sound was so mixed and enhanced that it resembled no "live" reality: All voices and music emanated from speakers with no depth and no stage-left or stage-right perspectives. I could have been listening to the cast CD.

Opera seems to remain one of the last venues to use natural stage sound. It may not be always be perfect, but it's thrillingly live -- and we could use more of that.

All the small mistakes and flaws in a performance have a name: charm.

Listen to the Bob Dylan and Johnny Cash duet of "Girl From the North Country" on the album "Nashville Skyline." In one part, they sing different words; that always makes me smile. Such moments are worth much more than "perfection." It's sad that inexperienced performers don't realize this.

The danger of using recorded "flawless" performance tracks in a live performance is that the potential for special live moments is eliminated, even though such moments are the reason many people go to live performances. Otherwise, it's a lot cheaper to stay home and listen to a CD.
