Like his best and most iconic works, the magic of William Basinski s 2013 album, Nocturnes, is in the glacial, inevitable decay of something beautiful. Tape loops of prepared piano composed and recorded more than 30 years ago reflecting, refracting, and disintegrating into a haunting sentimental haze, like losing a vivid memory to the natural deterioration of time. Nocturnes is two sprawling new works, begun in 1979 and completed in 2012. It is Basinski s first studio release in nearly four years.
