Evocative train sounds allow listeners’ own trains of thought to wander freely, in this emotionally captivating electroacoustic tone poem. As with other signature Shapiro works like Immersion and Liquid Compass, an expansive palette of shifting textures and density creates striking, unexpected contrasts. A remarkably seamless wash of acoustic and digital sounds offers new meaning to the term “prerecorded track,” as the piece picks up steam and arrives at a forceful, abrupt end. To perform the piece, you’ll need an audio system capable of playing the prerecorded audio tracks from a laptop computer via a small digital audio interface connected to an audio mixer.
