Immersion Composition Society

The Immersion Composition Society (ICS) is an underground network of composers, organized into independent groups, called lodges, who periodically spend one or more days composing unusually large volumes of music for the purpose of creating raw material for their new projects. There are several dozen publicized lodges in the U.S., Canada, Europe, and South America. The book The Frustrated Songwriter's Handbook details the ICS approach to creative songwriting.
