Reitzenstein's work has consistently taken him into processes exploring ways to interconnect nature, culture, science and technology.  He works in several parallel areas: indoor installation and sculpture using cast, spun and welded metals, wood, glass, photography, digitally processed images and other materials; large scale drawings; outdoor tree-based installations and sound art.  Among his numerous installation pieces are collaborative sound sculptures with Gayle Young.  These include two (1994, 1996) separate sound installation projects, "Tuyeaux Sonores" in Alma, Quebec, and Grimsby, Ontario respectively, and another entitled "Klang Bau; the Bunker Version" for the Sound Symposium in Newfoundland. "Sound Lodge", an interactive sound sculpture built with David Keane, was exhibited at The Nickel Arts Museum, in Calgary, during the conference "Tuning of the World", August 1993.  "Sound Lodge" also travelled to the Netherlands in May 1993, and in 1994 to Denmark for the International Computer Music Conference.
