Abstract: Identifying the connections between music and other artistic and academic disciplines—as well as diverse sociological phenomena—has been a central concern in my compositional process. In this lecture, using my three recent compositions as examples, I will discuss my motivations for such an interdisciplinary approach in the process of composing music. I will consider the role of composers in today’s society and the statement by geographer Oli Mould: “Creativity is, indeed must be, political.”
