After renovations, NY Philharmonic returns to Geffen Hall on Oct 7, 2009.

After a $550million renovation, the New York Philharmonic will be returning to Geffen Hall. On Oct. 7, Jaap van Zweden, music director, will lead a concert before an invited audience. The concert will be followed by a thank you speech to healthcare and emergency workers.

The Philharmonic announced Monday that the program will open with a “Home Festival”. Aaron Copland will perform “Fanfare for the Common Man”, a new work by Carlos Simon, and “Juba”, from Forence Price’s Symphony No. 4.; The overture to Rossini’s “Il Barbiere di Siviglia”; and the allegro of Beethoven’s Symphony No. 5.

Van Zweden will host a pair of one-hour concerts for free on October 8. Then, the first four subscription concerts of Oct. 12-18 will feature the world premiere of Marcos Balter’s “Oya,” light electronics and orchestra, John Adams’ “My Father Knew Charles Ives,” Tania Tania Le’s “Stride” and Respighi’s “Pines of Rome.”

The rebuilt hall will be smaller than the original 2,738, and have a capacity below 2,200. The third tier will disappear approximately two-thirds.

Concerts will be streamed free of charge in the lobby via a 50-foot-long Digital Wall. The hall will also include a small Sidewalk Studio.

To celebrate the reopening of the hospital, a pair of galas will be held on Oct. 26-28, with programs to follow. An open house will take place on Oct. 29-30.
