This work is a version of a project entitled Botasoneiro, undertaken in 2005 with saxophonist Iñigo Ibaibarriaga and sound artist Mikel Arce. The original work was based on the combination of baritone saxophone and electronic sounds in constant motion, both virtually and physically, due to the incorporation of rocking speakers.

The project was carried out in the church of San Felicísimo in Bilbao; thus, localizing the sound in was especially relevant in the process and the shaping in concert.
