The four films are set to music by the Spanish saxophonist Albert Cirera and the English double bassist Olie Brice. Cirera's playing is a sound sculpture in constant transformation. As if he were a sculptor of the ethereal, he moulds each sound with different techniques and instruments as if it were matter. Olie Brice, on the other hand, makes the whole body of his bass sing. He has the ability to play a fractal line that is as focussed as that of the great jazz bassists, but within a completely abstract framework.
