I'm one of those Luddites when it comes to scenery. Too often with a big musical, it overpowers what we're watching.
The best scenery for a musical recently for me was The Full Monty because we saw it, it registered and then we went back to watching the play.
Copenhagen had a wonderful set--a semi-circle of curved polished plywood that reflected the sound into the house and we did not need any mikes at all.
In 1970 Jo Melziener (sp) won Tonys for lighting and scenery for Child's Play. Accepting the scenery award after the lighting one, he confessed that most of his set design was there to hide the lighting instruments.
