To Omar Alvarez

A universe of sound is surrounding us ‘from within.’ It’s composed of our dreams, fears and longings. It only exists within our body, our own imagination. We want to share it; but there are no words, no possible descriptions. We are sitting on a meadow on a warm night, alone, watching the stars. Nobody is disturbing our thoughts. Nobody is limiting our space. We don’t have to rush anywhere; we have time to let go and to follow these sounding creatures… It’s not a nightmare; it’s just the interplay of our imagination.


Firmament — schlaflos [Firmament — sleepless] was realized in 2010 at Harvard University Studio for Electroacoustic Composition (HUSEAC) (Cambridge, MA, USA) and premiered on July 29, 2010 during the festival Inventionen in St Elisabeth-Kirche in Berlin (Germany). Thanks to Sarah Sun (recorded voice).
