Voices of Resistance: Music, Femicide, and Gender Justice in Spain and Greece examines how feminist musical practices across Southern Europe confront femicide and gender-based violence through mourning, memory, and political resistance. Drawing on detailed national case studies, the book argues that in contexts marked by institutional silences, legal gaps, or patriarchal backlash, music becomes a crucial feminist tool for naming violence, honouring victims, and sustaining collective demands for justice. In Spain, a rich genealogy of feminist musical activism intersects with a robust yet contested legislative landscape - functioning as emotional counter-publics that challenge antifeminist backlash and supplement the limitations of institutional responses. In Greece, where femicide lacks full legal recognition and media narratives often reproduce misogyny, music assumes an even more urgent role - transforming public grief into mobilisation and forging affective publics that hold state and society accountable. Across both contexts, Voices of Resistance positions music as a vital yet incomplete mode of feminist world-making, capable of unsettling silence and imagining more just futures.
