Gamelan Descending a Staircase is a composition of over fifty minutes whose instrumental sound materials were recorded at the Museum Dahlem Ethnologisches in the summer of 2013, during a research visit. A wide variety of Indonesian gamelan orchestra instruments were recorded specially for the occasion and later assembled into one surround sound composition that was then performed live. The gamelan may be thought of as a percussion orchestra and its instruments are mostly met allophones struck with mallets of various sizes, shapes, and materials: more than enough for Bumšteinas to rethink structures of the tradition and build a free form sound collage. The result is really fascinating and the compl rhythmic geometry of the work completely surround listeners, immersing them in timeless dreamlike atmospheres. Aurelio Cianciotta
