The MCO Foundation was founded in 2008 to support the Mahler Chamber Orchestra’s musicians, dynamic musical projects and diverse educational initiatives across Europe. Its mission is to bring the orchestra’s unique vision of classical music to the world.

The Foundation houses our Friend, Explorer and Patron Circles and is infused by the generous donations of supporters across the globe. It gives us the support we need to play far and wide, and to continue to boost the careers of talented young musicians.

The American Friends of the Mahler Chamber Orchestra want to transport the Mahler Chamber Orchestra’s music, educational projects and pioneering vision of classical music across the ocean to the United States of America.

Through the generous contributions of patrons from the US, the American Friends of the Mahler Chamber Orchestra enable a vital cultural exchange between the US and Europe and make it possible for the MCO to participate actively in the American classical music scene.

We invite our American Friends of the Mahler Chamber Orchestra into our inner circle, offering you benefits and special privileges, and inviting you to make special requests for involvement with our orchestra.
