Ultra rare private press of 'concrete' and 'electroacoustique' works by the students of the C.E.S. Paul Valéry (Thias) Issued in a limited pre paid order only, it is unclear how many were made, but what i can say is that in all my years dealing/collecting rare avant garde & experimental lps i have never seen this lp, must be less that 100. This lp isn't dated, but looking at the thickness of the disc and art work i would say early 60s. It comes in a beautiful gatefold sleeve with silk screened artwork realized by the students with Claude Thiberville. The works are very interesting, dark concrete poetry based on the poems of Henry Michaux, In the style of of Almuro or boisselet. Vinyl looks a strong EX+ but plays with soft tics throughout. VERY VERY RARE
