The New York-based Orchestra of St. Luke’s, a much-lauded ensemble made up of freelance musicians, has received an anonymous $5 million gift intended to allow the organization to start an endowment fund. “Orchestra of St. Luke’s has an annual budget of $5 million… The organization expects to raise about $280,000 this year from individuals and $250,000 to $300,000 from the board, with the rest coming from foundation gifts and ticket sales.”
