About
Interzone Frequencies is a 24/7 radio station dedicated to the deepest layers of underground sound. At its core is the Intercommunal Signal Network, active from 1970 to 1983, one of the most ambitious communal music ecosystems ever built. The majority of programming comes directly from ISN archives such as Aurora Weltklang, Spulenwerk, Tretmieder Tonband, Circuito Votivo, Resonanzwerk Kuppelstudien, and countless micro-labels. But Interzone Frequencies does not stop there. We also broadcast from parallel worlds of sound, including the Cologne-based Inner Space Records, the transnational network of Vortex Veil, and Italy’s Sabbia Rossa, known for its obscure spaghetti western and psych-folk crossovers. In 2025, we bring all of these materials together in one continuous signal, creating the most complete broadcast environment for experimental, communal, and freak-leaning music of the 1970s and beyond.
