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.

This single extended performance brings together a collective of improvisers playing low range instruments in order to build an acoustic sonic sculpture, from the quintet of Daunik Lazro on baritone saxophone, Jouk Minor on contrabass sarrusophone, Thierry Madiot on bass trombone & telescopic tubes, and both David Chiesa and Louis-Michel Marion on 5-string double bass.
