The American Association of Performing Arts Presenters holds its annual meeting in New York. “The conference functions as something of a freewheeling art marketplace where those who program (buyers) and those who perform (sellers) can get to know one another’s work. The principal conduit for all that creative networking is more than 1,000 performances around the city, continuing through Tuesday, when the association’s members scurry back to their artistic homes to program the 2004-5 season and beyond.”
