Installation for which a music piece for brass instruments and conch shells was composed, echoing two archive photographs that document the same group of teenagers playing in front of their school, in New Guinea, brasses (in 1930) and conches (in 1927). Each track was recorded onto a wax cylinder, medium employed for the original recordings of the orchestra, with two colours of wax currently used to cast copies of old ethnographic recordings. Both channels constitute the soundtrack of an anaglyphic video screened on a monitor: a still shot of the sea where the matching red and cyan channels produce colour gaps as waves approach the camera. Listening through headphones, the left channel plays the red cylinder, solely composed of brasses – hornpipes, trombones, tubas – while the right channel diffuses the cyan cylinder, solely composed of conches sounds. As a historical reinterpretation unifying the presented scenes, the installation confronts two obsolete techniques to simulate spatial depth to a more fundamental question of distance in cultural perception.
