Ryuichi Sakamoto's Spiritual Performance at The Shed.

"Kagami," a mixed-reality concert of Ryuichi Sakamoto's music by Tin Drum, features a virtual likeness of the late composer and incorporates flashy visual effects that accompany his playing. While the technology is miraculous, the experience feels like a wake in a laser tag arena. The production offers less a reflection than a perpetual afterimage, becoming an affecting meditation on grief. The performance is an effective transcendence of death, but so is any audio or video recording, or photograph, or any piece of art.
