[2] Archambault began playing the Native American flute in 1989 and has devoted intensive study to the earliest recordings of the instrument, dating back to the early 20th century.
He has also studied informally with the Native American flutists Kevin Locke (Lakota) and Edmund Wayne Nevaquaya (Comanche), and has collected songs of his Kichesipirini heritage, from elders in Canada as well as from archival wax cylinder recordings made in the early 20th century.
He was the first person to use the old warble technique (in which a single flute tone "splits" into a multiphonic oscillation) within the context of contemporary classical music.
Before taking this position he worked as a Project Architect in Rotterdam and New York City, working on the designs for the Prada Soho Store, the Lehmann Maupin Gallery in Chelsea, Manhattan (commissioned in 2001 and completed in 2002), and the Dee and Charles Wyly Theatre at the Dallas Center for the Performing Arts in Dallas, Texas (commissioned in 2004 and scheduled to be completed in 2008).
Prior to joining OMA in 1999, and helping to establish its New York office, he worked for Pasanella+Klein Stolzman+Berg Architects in New York on the Pratt Stabile Hall Dormitory, and for Frank O. Gehry and Associates in Los Angeles on the Samsung Museum of Contemporary Art and the Walt Disney Concert Hall.
