Your client wants to go out for a one-off concert event. It makes sense to use last year's set for financial reasons but you need to spice it up a bit. What do you do? If you're designer Warwick Price and your client happens to be Luther Vandross, you look for just the right element to set off the show. How about a little water, a little fog, and some Plexiglas® truss? That's exactly what Price did for Vandross' recent four-night set in February at Radio City Music Hall.
