Richard Chartier (USA, 1971), also known as Pinkcourtesyphone, is an ultra-minimalist composer who, starting with "Direct, Incidental, Consequental" (Intransitive Recordings, 1998 - 3particles, 2003), focused on "silence music" a la Bernhard Günter and "deep listening" a la Oliveros. His microscopic exploration of the space between sounds and silence, is best exemplified by his fourth solo album "Series" (Line, 2000) and by "Decisive Forms" (Trente Oiseaux, 2001).
