Released on 15 May 1980, the "Bloody Revolutions / Persons Unknown" 7'' split single by Crass and Poison Girls stands as a definitive landmark in the UK anarcho-punk movement. Issued via Crass Records, the joint release served as a political fundraiser, with all proceeds dedicated to establishing an independent, self-managed music venue for the punk community at London's Zig-Zag Club. The record is famously housed in a signature, high-contrast black-and-white fold-out poster sleeve designed by artist Gee Vaucher, featuring striking anti-establishment imagery of key political and religious figures from the era.
Musically, the split captures both bands at the height of their creative and ideological influence. Side A features Crass's "Bloody Revolutions," a chaotic, blistering critique of traditional political uprisings that argues violent revolution merely replaces one oppressive ruling class with another. Side B showcases Poison Girls' "Persons Unknown," a brooding, rhythmically driven track led by Vi Subversa's distinct vocals that addresses state surveillance, police overreach, and the systemic erasure of individual dissent. Together, these two tracks offered a cohesive manifestation of the early 1980s DIY ethos, blending uncompromising lyricism with concrete grassroots activism.
