Jean-Luc Guionnet

Points sans surface is a composition by Jean-Luc Guionnet for the Un Ensemble, a large ensemble created in 2012 under the direction of David Chiesa. The piece includes a sound system for 25 musicians and 8 speakers. It is also a visual experience generated by light. The general device consists of an acoustic and electroacoustic spatialization of sound. The audience is surrounded by musicians and speakers. Each instrumentalist is picked up by a microphone connected to a mixing console offering the possibility of amplifying these sources and broadcasting them again, according to the needs of the room. The sound then takes on a three-dimensional dimension: an acoustic distance (musicians), a proximity (loudspeakers), a verticality (musicians and loudspeakers are placed at different heights). Jean-Luc Guionnet indicates partition positions, and sometimes shouts them out. The musicians throw diagonals, correspondences, throws towards the walls, the floor, the ceiling. Sometimes, we perceive blocks or, on the other hand, lost solos. Beyond the autonomies of play, timbres and tempo, an indescribable feeling of sound invasion of the air settles in, disappears, returns, we hear like an orchestra that would scrap with another, elsewhere.
