In 2004 Sid scored his first short film “Temple Tumble” by Niels Philipsen. After that he scored a number of short films that same year, one of which made it on national television (Netherlands). One of the most important projects came in 2005, when Sid got in contact with the award-winning director Jeremy Haccoun to score his shortfilm, "Paradox". After this Sid was introduced to conductor Lex Veelo of the Hofstads Jeugd Orkest, the oldest Youth Orchestra in the world. He got commissioned to write a concertpiece for them to perform at the National Youth Orchestra Contest.
