Best known for his ambient, slowly evolving sound compositions such as The Disintegration Loops (2002), tape-loop tinkerer William Basinski presents his most recent piece, Nocturnes. Originally recorded in 1979, the piano metallic tape loop used in Nocturnes was stored for more than 30 years, gradually being degraded and transmuted by time. Basinski has further altered the identity of the sound by removing the attacks of the piano and overlaying them, creating an underwater-like atmosphere that is strangely recognizable as the ghost of the piano.
