I present here some results of my researches on sounds, music and spoken or sung words. I produce tracks with "BPM pro Mixer" by Alcatech, from playlists of musics that inspire me,sounds collected from own recordings or other sources, words spoken or sung by myself, or extracted from audio books. I mix two randoming play lists, running together at the same time along, applying level modulations, and sampling from time to time the playing files, in an improvised session. I wish I can share with you the pleasure of my work, as you pay attention to these quite experimental creations, that can refer to the "musique concrète" thought processes.
