AbstractMembers of the rock band Henry Cow co-founded Music for Socialism in early 1977 with the assistance of several associates in London's cultural left. Their first large event, a socialist festival of music at the Battersea Arts Centre, gathered folk musicians, feminists, punks, improvisers, and electronic musicians in a confabulation of workshops, performances, and debates. The organization would continue to produce events and publications examining the relationship between left politics and music for the next eighteen months. Drawing on published sources, archival documents, and interviews, this article documents and analyzes the activities of Music for Socialism, filling out the picture of a fascinating, fractious organization that has too often served as a thin caricature of abstruse failure compared with the better resourced, more successful, and well-documented Rock Against Racism. As important as the latter was to anti-racist activism during the rise of the National Front, it was not concerned with the issues that Music for Socialism considered most important – namely, how musical forms embody their own politics and how musicians might control their means of production. Affiliated with the Socialist Workers Party (UK), Rock Against Racism produced massive benefit concerts and rallies against the fascist right, drawing together musicians and audiences from punk and reggae. The much smaller events of Music for Socialism enrolled musicians from a range of popular music genres and often placed as much emphasis on discussion and debate as they did on having a good time. The organization's struggles, I will suggest, had less to do with ideological rigidity than it did with the itineracy and penury of musicians and intellectuals lacking support from the music industry, governmental arts funding, labor organizations, or academia.
