N°20/58 is a piece by Heiner Goebbels written for Erwan. It reflects the composer's curiosity for the performer's stage presence, as well as his desire to work on the perception of sounds as much as the sounds themselves. Thus, N°20/58 is a piece written for a moving ringer. Created outdoors in a location chosen by Heiner, Erwan approached the audience in a slow ascent on foot that physically put his performing body to the test. The music gradually revealed the public space, making it ring with the bagpipe's familiar power.
Then, the composer and musician worked together on an adaptation for a seated audience in a closed hall. The piper then finds himself outside again, outside the hall, to start playing. It's then up to him to find a way of getting closer to the ears that are listening to him, and to render this piece for each venue and each audience. The quotation of two Bach Arias, linked together by a multiplication of trills, provides him with a score to guide his way.

Eliane Radigue, on the other hand, was inspired, on discovering this instrument, to contain the sound volume of the bagpipes to impose an intimate and delicate relationship that characterizes her work. It's no longer a question of composing in an ample movement, but of writing to reveal a reduced space thanks to held sounds and the harmonics that reveal themselves. Erwan is seated on a quasi-static chair, very close to the audience.
Eliane continues to search with this piece for, in her words, "a sound universe in its integrity, one in which each person, each listener, can hear, find, rediscover and create his or her own inner music, letting themselves be lulled and traveling endlessly".

Two Pages by Philip Glass was originally conceived as a piano continuum. By transposing it for his bagpipes, Erwan plays with the amplitude he finds between the continuous breath allowed by the bag and the drones, and the velocity of his fingers. Two Pages becomes a score that allows him to work his instrument extensively. The sound of the bagpipes takes up all the space until it becomes obsessive, obsessive until it stops short, to surprise once again.
