HaChau 864 is a music intervention in which musicians play their instruments from the windows
of apartments at Harburger Chaussee 105 to 113 in Hamburg. Musically it can be described as
a collage of musical segments in different formats and styles, in which defined segments of
soloists and duets alternate with moments of improvised tutti. Conceptually, this intervention
addresses the lack of pleasant public spaces to gather and the noise pollution of the area. In
addition, a distinguishing feature of HaChau 864 is that both the logistics and artistic design
were developed in a collaborative effort with local residents. This 30-minute intervention was
presented on a warm Saturday in June within the program of the festival 48h Wilhelmsburg
2017 and was part of W-Burg, a two-year exchange project with composers from Brooklyn’s
Williamsburg and Hamburg’s Wilhelmsburg
