It's the anniversary of one of the most controversial moments in music: the premiere of 4'33" by John Cage in Woodstock, NY, by long-time Cage performer and collaborator David Tudor. This also means there has been 61 years of every opinion imaginable on the validity of Cage's seminal work, and perhaps his entire oeuvre. Cage noted that at the premiere the audience missed the point, that there is no such thing as absolute silence. You can perform this work anytime, anywhere and if you need a score, we've provided one below (as well as a video of a full orchestra performance).
