XY is a new work by Marina Rosenfeld for ONCEIM, featuring one organ, two trumpets, two trombones and two euphonia. Like many of her works since her early experiments in feminist and improvisational music-making strategies in the 1990s and 2000s, XY calls into being numerous consecutive and simultaneous relationships between players that are contingent on perceptions of difference and similarity, distance and nearness. Fundamentally social in structure, XY exploits the listening propositions brought into being by spatial displacement, aftersound, and what she has called “disunisons” — gradual movements away from unisons and towards other kinds of attentional organization.
