An obscure classic from the 1970's Belgian jazzy prog scene that has become a much sought after piece in the collector's market since it was originally released in 1974. Highly inspired by both the UK's Canterbury scene and the zeuhl sound, the debut album by Cos has been compared to the likes of Soft Machine, Gong, Hatfield & The North, National Health, Gilgamesh, Egg, Placebo, Magma or Zao, with Pascale Son's unique wordless vocals and nonsense syllables singing in a voice that some sources have compared to Flora Purim'. The origins of Cos date back to the second half of the sixties when Daniel Schell joined forces with Jean-Paul Musette, Pascale Son and Robert Pernet to form Classroom. When Classroom split, Daniel Schell and Pascale Son moved ahead and formed Cos together with Charles Loos, Alain Goutier and Bob Dartsch. They produced an experimental jazz rock sound linked to the influences above mentioned, but without being mere copycats since they always managed to keep to their own personality. The album was released on the small obscure label Plus, and has arised interest not only among prog-rock psych-heads and jazz experimentalists, but also among those looking for breaks and bits to sample.
