Weerkaatsing is the first collaboration by Rutger Zuydervelt (Machinefabriek) and Sietse van Erve (Orphax), both active players in the Dutch experimental electronic music field. While their paths did cross many times at concerts either as visitors or as performing artists, never before these prolific musicians got together. And as with so many collaborations also this one has a story behind it: Reflectie (Orphax) The idea behind this collaboration started in 2007, when Rutger released his EP Stofstuk and following this the remix album Kruimeldief. For years since the release I was intrigued by this little piece and the various remixes, and always had the idea of making a remix myself (and actually to start a series of unrequested remixes). Finally in 2016 I took the time to really work on this Stofstuk remix. With some magic and other forms of witchcraft I created the almost 20 minute long drone piece Reflectie, based solely on the Stofstuk piece. I tried to put a real Orphax touch to the work, but without losing the true Machinefabriek sound. As such it really felt for me as if we did a collaboration; and it was screaming for more. So I told Rutger about this and after I sent him the piece the idea came he would also remix one of my works.
