NEW YORK, September 11, 2006 – Pachelbels Canon, even Brian Enos version, isnt the sort of music you expect at a runway show. And a bucolic backdrop of rolling hills behind a catwalk that, in turn, was painted lawn green and elevated over a river of mint candies isnt the kind of setting you see every day of fashion week, either. But Marc Jacobs has such a surfeit of cool, he got away with both—and then some—at a spring show that was strangely beautiful (as ever), if a little esoteric.
