The drummer and composer Tyshawn Sorey has a lovely phrase to describe the practice of improvisation: “the adornment of time.” It’s the title of his gorgeous new album with the pianist Marilyn Crispell, recorded live in the fall of 2018 during Sorey’s residency at The Kitchen, a performance space in Chelsea. The music begins in near silence, punctuated at first by what sounds like knocking, or maybe hammering. It’s followed by thudding noises, strokes of a piano’s strings, a drum roll so subtle it might be an aural illusion, a crash of cymbals, the tapping of a glockenspiel, the pattering of piano keys. Over the next hour—there’s only one track—the collaboration’s architecture comes into radiant focus, gradually acquiring such physical power that you feel a kind of shock, and even sorrow, when it ends.
