A previously unpublished and obscure sound work by the famous artist Brion Gysin... ‘Bruits du Beaubourg’ or, quite literally, the concrete noises coming from the builder’s yard of the Beaubourg recorded on location in June 1977. Different layers of sounds that, with the natural development of the piece, create an hypnotic soundscape. Abstract and con- crete. The recording comes from the original masters that Ramuntcho Matta personally got as a gift from Gysin himself; and Matta generously offered them to Alga Marghen. After lis- tening to the pure quality of this peculiar work it was decided to issue it in a LP edition lim- ited to 350 copies, available now for the first time.
