The terms of the contract were not made available.
The orchestra will return to work for today's 2:30 p.m. performance of Radio City's Christmas Spectacular. During the two-week conflict between musicians and management, the musicians were replaced by recorded music.
In a statement, David Lennon, president of Local 802 of the American Federation of Musicians, said, "We have reached a deal on a long-term contract that will guarantee live music at Radio City Music Hall for years to come. This is a win for the musicians, management, the city of New York, and audiences from all over the world."
New York mayor Michael Bloomberg helped bring about the agreement by providing a mediator for the two parties, which had been in negotiations for months before the musicians went on strike on November 2, over a disagreement about salaries and overtime. The musicians showed up for work on November 3, but were told that the show would go on without them.
Bloomberg said in a statement that the new agreement "announces to the world the official start of New York City's holiday season and affirms that our city will continue hosting spectacular events, and attracting countless new visitors."
