At World Stages, 'Les Souffleurs Commandos Poétiques' is an inspired artistic intervention

Stop. Breathe. Smile. You're in the hands of angels of tranquillity. They look fabulous in their individualized black outfits -- chic boots here, a bowler there. They're ultra-hip and cross-cultural, from France and Japan. They move slowly, coolly, among the hundreds of people lined up for something else entirely outside the Kennedy Center late Friday afternoon. They carry delicate black parasols.
