This video essay discusses how contemporary artists might directly address some of the philosophical and political challenges of a material approach to instrumentality through creative practice. I present and discuss the practical approaches taken by musicians who create and collaborate with instruments as a central part of their work: Khabat Abas and Sam Underwood. In examining their creative practice both creating and working with musical instruments, I examine how these artists navigate the agential and material aspects of the instruments and systems they create, in parallel with the conceptual ideas that they bring to and derive from such systems.
