Dark sound carries the dense cultural weight of darkness; it is the undertow of music that embodies melancholy, desire, grief, violence, rage, pain, loss and longing. Compelling and unnerving, dark sound immerses bodies in the darkest moments and delves into the depths of our hidden inner selves. There is a strangely perverse appeal about music that conjures intense affective states and about sound that can move its listeners to the very edge of the sayable. Through a series of case studies that include Moor Mother, Anna Calvi, Bjoerk, Chelsea Wolfe and Diamanda Galas, D Ferrett argues that the extreme limits and transgressions of dark sound not only imply the limits of language, but are moreover tied to a cultural and historical association between darkness and the feminine within music and music discourse. Whilst the oppressive and violent associations between darkness and femininity are acknowledged, the author challenges their value to misogynistic, racist, capitalist and patriarchal power, showing how dark sound is charged with social, creative and political momentum.
