Silence has a lot to tell us. Even the sounds we forget to hear are always narrating the world. Few humans really know how to slow down and tune in as well as the once and future king John Cage, maestro of underdog aural landscapes and forgotten frequencies. His particular magic was a balm, koan and sigh for a natural and unnatural world that does its best, frequently fails and always tells a good story. Born in Los Angeles September 5, 1912, his compositions are being celebrated just in time by the LA-based Society for the Activation of Social Space through Art and Sound (SASSAS) with a series of classes for kids September 3-5, Kids Play Cage, with three foci: What is Music?, Silence and Chance, culminating in a free performance by the students September 8. The class costs nothing and is open to the public —- register your small person as soon as you can, though, and get a spot at the performance.
