Madonna performed last night in New York City for an exclusive crowd that included Lindsay Lohan, Zachary Quinto, and her ex Sean Penn as she launched her new Art for Freedom initiative, which encourages members of the public to submit ‘video, music, poetry, and photography to a new website. The event at the Gagosian Gallery in Chelsea on 21st Street (as opposed to the one three blocks away on 24th, or the other two uptown) featured the screening of a film showing the singer playing a prisoner and a jailer. Madge also performed a new song onstage with a masked dancer who turned out to be her young son Rocco. As part of the launch, the film, directed by photographer Steven Klein, was also screened at various locations around the world, including London, Los Angeles, Toronto, Paris, and Berlin. A statement about the project, posted on the Artforfreedom.com website, explains, “Madonna & Steven Klein invite you to start your own revolution of love. We have created this platform to give people around the world an opportunity to answer the question: ‘What does freedom mean to you?’ Express your personal meaning of freedom and revolution in the form of video, music, poetry, and photography. Join the revolution by submitting your art for freedom below, or by tagging your posts #ArtForFreedom.” So there. The “secret” is out.
