Musical experiences, somehow, often escape materiality. Listeners tend to focus on the way music makes them feel, and its study is often grounded in the socio-cultural ideologies of musical genre and style. Yet, music relies on material infrastructures in how it is produced, consumed, and disseminated. This ensemble of listening-artists' investigates such musical infrastructures, tracing the complex supply chain networks that make up our modern musical experiences. Through readings, listening, and exploratory sound-art projects we will re-trace these musical-material chains, rethinking our involvements with musical production and consumption.
