- Lontano
- mixed choir and metronomes
Press:
'Lontano' was the name of the opening piece for solo metronome, mixed remote choir and clicking sounds by Martin Willert. Darkness reigned in the hall, some light came through opened doors and a glittering spotlight on the metronome. Highly sophisticated, how the slow basic clock rate of the metronome, singing and un-locatable clicking overlaid gradually netlike, then again slowly diffused like small drops.
/ Irene Constantin, Neues Deutschland, 2010-04-16
'Lontano' hieß das Eröffnungsstück für Solometronom, gemischten Fernchor und Klickgeräusche von Martin Willert. Dunkelheit herrschte im Saal, etwas Licht kam durch geöffnete Türen und ein gleißendes Spotlight auf das Metronom. Hoch diffizil, wie sich dem langsamen Grundtakt von Metronom und Gesang ein un-ortbares Klicken und Klacken nach und nach netzartig überlagerte, dann wieder langsam vertröpfelte.
