Official Music Video for Dusk Tempi (Field Works / Eluvium) Music written and recorded by Matthew Robert Cooper. Filmed by Anna Powell Teeter. Edited by Asa Gauen.
Stuart Hyatt returns with another sonic wonder in the Field Works series, bringing the listener into truly uncharted acoustic territory. Ultrasonic is perhaps the ﬁrst-ever album to use the echolocations of bats as compositional source material. For this special album, Hyatt has assembled an extraordinary group of contributors: Eluvium, Christina Vantzou, Sarah Davachi, Ben Lukas Boysen, Machinefabriek, Mary Lattimore, Felicia Atkinson, Noveller, Chihei Hatakeyama, John Also Bennett, Kelly Moran, Taylor Deupree, Jefre Cantu-Ledesma, Julien Marchal, and Player Piano. Ultrasonic is part of a broader storytelling project about the federally endangered Indiana bat. Generously funded by the IUPUI Arts & Humanities Institute and the National Geographic Society, each album contains an ofﬁcial printed booklet of The Endangered Species Act of 1973.
