Rens Machielse composes and produces sound and music for moving images such as fiction, documentary and animation in close collaboration with Willem Schneider (Studio Masch). Both have long standing and award winning careers as composer and sound designer. Rens has a particular interest in projects that offer time and space for experimentation with sound and music in order to deepen the narrative of the moving images, and provide them with an extraordinary soundtrack. He has done so in the past with directors such as Nicole van Kilsdonk, Paula van der Oest, Simone de Vries and Pieter-Rim de Kroon. His music has been awarded with a.o. the Stemra Music Award and a Gold Medal Best Original Score New York Festivals. Examples of his music can be found on SoundCloud.
