Echohaus was recorded in and around Levin's Electric Avenue studio in the basement of WESTWERK, a former squat and cultural centre for non-commercial art and music in Hamburg. A special recording technique was developed for the project whereby the musicians played simultaneously in separate rooms, connected to each other only by headphones. This was done in order to achieve a lively, cinematic sound that made use of the particular dynamics of the rooms and amplified mechanical details. The rooms, each of which had a different acoustic character, were used as natural echo chambers. Kubin and the composer Burkhard Friedrich, former member of Ensemble Intégrales, provided the musicians with simple graphic scores or basic descriptions of the compositions; all subsequent material was developed on the fly. Kubin was in the mixing room giving instructions and suggestions, while the musicians played and improvised, adding their own ideas to the project.
