In this article, I show how the Dialita women’s choir uses music to contest the ongoing denial of state-sponsored violence that followed the Indonesian tragedy of 1965–66, particularly as it impacted women. More specifically, Dialita uses their experiences and positionalities as women to perform an alternative collective memory for younger generations of Indonesians. Composed in prison, Dialita’s musical repertoire memorialises the affects and effects of imprisonment, exile, trauma, and survival. Due to government censure and public condemnation, the songs had been silenced by the Indonesian state and hidden underground from the public since the Indonesian tragedy. In the early 2000s, the women of Dialita formed a musical group and courageously began performing in public, collaborating with young musicians and recording the songs. I contend that women’s collective singing is an act of critical remembrance, opening a new front in struggles for truth and reconciliation, especially when juridical appeals and strategies have been rebuffed.
