0'32''/9'06'' is a piece composed for live electronics and interactive visuals performed by a keyboardist/pianist. It uses a minimalist language and has been conceived and composed for live interpretation. It is based on two almost identical short samples extracted from Arvo Part's famous piece Spiegel im Spiegel written in the composer's characteristic tintinnabular style. The two samples have a duration of approximately 10 seconds. The first sample appears at 0'32'' and the second one at 9'24'' in the recording where have been extracted from.
Part's piece Spiegel im Spiegel in German means "mirror in the mirror" and is referring to the infinite reflections of two parallel plane mirrors. S0'32''/9'06'' attempts to extend this idea into a more complex topology where those infinite reflections are re-diffused and spread across the space. A sustained note becomes a repeated arpeggio and finally an infinite sonic grain before becoming again a sustained note.
The following raw footage was taken from a live performance (sound diffusion) that took place during the Festival Musica Viva 2015 in Lisbon.
