Pierre Schaeffer

          Pierre Schaeffer invented an electronic, stereophonic sound, called concrete music.  His interest in music, evolved with his occupation as a broadcaster with the ability to practice with sound. He spent much of his time at Radiodiffusion Francaise experimenting with mulitple different sounds, one normally would not label as music.  He played with the speed of sounds and integrated them together.  The sounds were also mixed with natural recordings, he had done himself.

             In 1948, radio stations equipment was limited to shellac record players, mixing desks, mechanical reverberation and microphones.  With the combination of these appliances musicians such as Schaeffer, could loop, extract, and filter songs.  Three years later he created a Researching Group for Concrete Music that attracted many composers, who would later become famous for their work.  His creation of the phonogene was on of the first machines to transform sound.  Concrete music is still being practiced. Here is a link I found online of a super strange one.  Today he serves as one of the most influential musicians of our time.
