Book excerpt: The internationally acclaimed event producer shows his ideas and inspiration for ultimate and intimate celebrations What defines a truly great party? Most of all: generosity of spirit. In his first book, Bronson van Wyck, the man Vogue called 'The Wizard of Oz of New York party planning,' distills the essential pillars of the art of celebration into one volume, with examples drawn from his many successes - and, admittedly, a few entertaining failures. Lusciously illustrated with images from van Wyck's most spectacular events, this is the perfect primer on throwing parties that are as much fun to give as they are to attend.
