For decades, you never heard the name “Koma” without “Eiko” preceding it. Eiko & Koma, partners in life and in art, moved as slowly as moss grows and as organically. They seemed, in the course of an hour or two, to shed obstreperous humanity for the elemental. Then, in 2004, Koma sustained an ankle injury and Eiko began to perform solo. By 2017, he had recovered enough to follow her—with his own solo project! Koma’s multi-year Ghost Festival is an avant-garde take on the Buddhist Bon festival with which he grew up. Every year in Japan, participants move between the living and the dead. Koma’s dead are a motley crew—“friends, parents, siblings, streets, fields,” he says. He responds with equal variety. Somehow, without each other, Eiko and Koma have become less like nature and more eccentric. They remain unmissable. —Apollinaire Scherr
