This new release on Kohlhaas is from a quartet whose music is something writing and improvisation. Pequod is one of the project dealing with the codification of the language of "free improvisation" whose path is now on the exploration of spaces rather than on dissonances or noises related to social situation. So the reverb of the place where music is played has a role when it takes the musician into a state of introverted playing, and listening, where quiet nuances of sound are generated in the surrounding silence.
This release sounds as a single track in four movement; the slights masses of sounds which are the base of "Ex-I" depicts a sense where meditation is paired with action. "Ex-II" is, instead, a track based on silence where all sounds start barely audible to gradually evolve in a final part. "Ex-III" has twitch of sound that tie together a noisy first part and a quiet second part. The guitar's ostinato that opens "Ex-IV" is the skeleton of a track where all sound are in relation to the tone until they are left alone to close this release as a slow movement to silence.
This is that kind of release where instrument are explored as sound source rather than canonical musical instruments so it's a research for subtle tones and abstract shapes that immerse themselves in the environment to even disappear in the today's soundscape where all noises raise their volume. In a quiet environment is an education to listening.
