Developers provide space for 9/11 musical remembrance.

Fisher Brothers, Paramount Group, Tishman Speyer and Vornado Realty are among the many city developers donating space for a city-wide musical event to mark the anniversary of September 11, 2001.

On the fifth anniversary of the tragedy, thousands of musicians will fill the skies across the country and the world with music as part of the Fifth Annual September Concert, a music festival launched in 2002 to spread a message of peace through the power of music.

From noon until 5 p.m., musicians will perform in over 50 parks and other venues around New York City, pausing at 2 p.m./EST for a sing-along of this year's anthem of hope and peace, "All You Need Is Love" by The Beatles.

Development partners who have donated space and resources for the free shows include Fisher Brothers Management, Paramount Group, RFR Realty, Reckson Associates Realty Corp, Rudin Management, Tishman Speyer Properties, Vornado Realty Trust and many more. Additional organizations involved include Musicians on Call and Musicians Under the City of New York. Fox Television serves as the broadcast media sponsor.

Special concerts planned for September 11 in New York City include the NYC Police Band performing at Rockefeller Center; the New York Pops at the United Nations, and the New York Choral Society at St. Patrick's Cathedral. Other concert venues include Central Park, Herald Square, Madison Square Park, Union Square, Washington Square Park, The Bitter End, The Living Room, the Jazz Standard and many more.

Concerts are now planned in 20 cities--including 13 U.S. cities and seven more internationally. In the U.S., concerts are planned in Boston, Oakland, Phoenix, San Diego, San Francisco, Sarasota and a special U.S. Navy Band performance at the U.S. Navy Memorial in Washington, D.C. International cities involved in celebrating this global day of peace include Beijing, Cairo, Kobe, London, Paris and Tokyo, with the list continuing to expand.

"We are so pleased to announce this expansion of The September Concert to cities across the country and around the world," said Haruko Smith, president, The September Concert.

"We are deeply gratified by the enthusiasm people around the world have had for the project. Everyone understands the universal language of music.

"Our goal is to use the power of music to spread the message of peace throughout the world, and our expansion signals that we are definitely accomplishing that."

All concerts are free, and feature all kinds of music, from hip-hop and pop rock to classical and world music. They are organized and performed by professionals, semi-professionals as well as up-and-coming newcomers.

In 2005, the September Concert Foundation organized 117 concerts with more than 2,000 performers. Although primarily focused in the New York area, the Foundation continues to expand and has partnered this year with a variety of national and international groups.
