ECAS (European Cities of Advanced Sound and related arts) is a network of independent non-profit organisations across Europe, all dedicated to advancing sound cultures, music and related arts.
All members of ECAS have spent years crafting unique festivals and events, each with its own identity grounded in strong local connections and context.

Activities within the events and festivals organised by ICAS members include concerts, performances, commissioned work, exhibitions, participatory projects, educational workshops, conferences, presentations, panel discussions, publications and informal spaces for knowledge-sharing within and between fields. As cultural entrepreneurs, ECAS members measure their success by valuing quality, critical reflection, innovation and creative exchange.

The network aims to spark dialogue, exchange ideas and knowledge, and provide mutual support for European organisations working with advanced sound cultures and related arts. Its goal is also to support members in their activities to develop and promote independent music and sound creation within their specific localities.
