RSF is working with CLSI to develop new music venues for new music in Paris, including Reid Hall (Columbia University in Paris) and the Théâtre Ile Saint Louis Paul Rey.

Matthew Greenbaum, a NYC native, moved from Brooklyn to Paris in 2024(?), an exemplar of the inevitable brain drain we see when things deteriorate in the US. In Paris he met Parisian-American composer/psychologist Gérard Pape, who, for a time, was the director of Les Ateliers UPIC (now CCMIX). Pape & Greenbaum began imagining a way for music to thrive in Paris, hoping to open up Paris to a broader range of new music after the stranglehold of Boulez and IRCAM. Greenbaum compares the hegemony of Boulez to that of Lully.

The Circle for the Liberation of Sound and Image (CLSI) is a Paris-based ensemble created in 2007–2008 by Gérard Pape. Designed for the interpretation of graphical scores with real-time electronic devices, the group also acts as a laptop orchestra and has been directed by both Pape and Paul Méfano, performing at festivals like the Stockhausen festival.
