In the early 1980s Deutrom was a member of a Los Angeles based art co-op called Werkgruppe founded by D. Emily Hicks and Daniel Joseph Martinez. Lori Black was also a member. Deutrom contributed several multichannel soundtracks for Hicks' and Martinez's conceptual pieces culminating in a 23 channel synthetic audio environment for the 1984 Olympics Arts Festival installation entitled "The Peoples of Los Angeles". The piece included multiplex holograms of individuals from Los Angeles reciting soundtracks of their experiences in the region against a constantly shifting holographic audio ambience. Other collaborators included physicist and holographer Lloyd Cross, holographer Sharon McCormack, artist Abbe Don and musician Chili Charles. The exhibition was held at the University of Southern California Atelier Gallery in Santa Monica. A catalog was published that included 3-D glasses. "The Peoples of Los Angeles" was reviewed in The Los Angeles Herald Examiner. It was also reviewed in The Los Angeles Times.
