A 2012 project was curated by Juraj Kojs to celebrate the centenary of Cage's birth, titled On Silence: Homage to Cage. It consisted of 13 commissioned works created by composers from around the globe such as Kasia Glowicka, Adrian Knight and Henry Vega, each being 4 minutes and 33 seconds long in honor of Cage's famous 1952 opus, 4′33″. The program was supported by the Foundation for Emerging Technologies and Arts, Laura Kuhn and the John Cage Trust.[9]
