On January 12, 2017 at San Francisco's Grace Cathedral, Lévy Gorvy presented the third U.S performance of Yves Klein's groundbreaking Monotone-Silence Symphony.
Over one thousand people were present to experience this moving and transcendent work, which unfolds as an orchestra of musicians and singers holds a single continuous tone for a twenty-minute period, followed by twenty minutes of absolute silence.
