Extraordinary solo percussionist Evelyn Glennie is the subject of this documentary, which explores the connections between human sensation, time, sound and rhythm. Glennie, an accomplished musician who's been deaf since age 8, is so sensitive to vibration that she essentially hears through the sense of touch. Here, she's captured in improvisational solo and group performances in intriguing spaces, from a New York City rooftop to a Zen garden.
