Mason's work is the result of an intensive exchange with the musicians of ensemble recherche. He leaves the Well-Tempered Sound to let floating states arise and disappear. At the tonal center is the piano, with an enraptured mood that appears like a flicker above the sounds of the ensemble. Mason works four-dimensionally with space and time. Sounds move along their paths like meteors, fade away and dive into infinity. He composes sounds, noises and spaces in the course of time. At the end of the piece, the cello is left all alone, lost in an ecstatic semi-improvisation, while the other instruments wistfully penetrate into the distance.
