Vivaldi’s Business Plan — In the U.S. everyone thinks St. Martin-in-the-Fields is an orchestra. In the U.K. everyone thinks it’s a homeless shelter. The Academy of St. Martin-in-the-Fields is over 50 years old and St. Martin’s today, with 350 concerts a year, offers the fullest concert program in the U.K. Meanwhile the Connection at St. Martin-in-the-Fields is the busiest homeless day center in the country. And it’s all based on Vivaldi’s ministry to orphans.
