A collaboration with National Geographic Society, Ultrasonic is perhaps the first-ever album to use the echolocations of bats as compositional source material. Grammy-nominated artist and musician Stuart Hyatt returns with another sonic wonder in the Field Works series, bringing the listener into truly uncharted acoustic territory. 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.
