Composed by erikM and performed with the Dedalus Ensemble, these pieces started through acousmographe recording of sounds outside of human hearing, transposed into notes and scored to be interpreted by musicians while immersed via headphone to mimic the sounds of cetaceans, then rearranged in the studio to create the annotated compositions heard on these carefully recorded compositions.

The 2nd part of a trilogy for guitar and sinetones composed between 2015-18, alongside "What Might Occur (Rereadings of Triadic Memories by Morton Feldman for guitar and sinewaves)" (2015-17) and "Un Lloc Entre Dos Records" (2017); this work, originally written in 2016, and revised in 2018, is heard in a recording at GMEA, France, with guitarist Benjamin Maumus.
