Léo Kupper had an interest in making music that was totally from electronic sounds, and not with or the addition of 'real' instruments. What his music is a landscape of some style that makes an aural statement that in turns can be scary sounding. The electronic noise often sounds like a form of nature to me. I hear dolphins (not in a new age fashion), electrical storms, birds, crickets, waves hitting the beach, and perhaps noise of passing vehicles - either an automobile or train. There is something human about Kupper's work, in that it's not about electronics specifically, but how those sounds interwind within the natural life.
There are works on this double album that features vocals. Not singing mind you, but female voices that are either speaking in a foreign language or used as a texture to the overall music. These pieces remind me of Luciano Berio's work with the Swingle Singers. The Italian composer made a lot of vocal music that were either based on literary text or poems. On one of the works here on this album, "L' enclume des forces" features text by Antonin Artaud. Overall there is a sinister quality to the music. Kupper captures a sense of dread or anxiety.
