The Foundation was created in April, 2002 for the sole purpose of organizing an annual citywide music festival in New York, in remembrance of September 11th and a celebration of our universal humanity. Our vision is to mark this day as a day of music and prayers for a peaceful world year after year, and build it to become the largest Peoples' Concert in the world. In 2009 its concerts already spread many continents, including Europe, Asia, Africa and North America.

The September Concert is based on the principles of musical equality, freedom, and accessibility, and the spirit of giving. All concerts are free.
