"A few years ago I executive produced Sonic Geometry II along with Eric Rankin and Alanna Luna, (a friend and colleague) after learning of his work in Sonic Geometry I (this video). This thought-provoking first film was his vision for many years. The film’s message is universal and describes the mathematical link between geometry and music. In so doing, it spans ancient history, philosophy and science in an attempt to answer some of the bigger questions that continue to face humanity today. I hope you enjoy Eric’s creation."
