Capturing the rhythmic and melodic nature of their communication.

Stuart Hyatt is releasing a new album under his Field Works alias, titled Ultrasonic, this May via Temporary Residence.

Recording the echolocation of the endangered Indiana bat, Myotis Sodalis – which communicate at higher frequencies than humans can hear – was “akin to taking pictures of invisible people on a film camera,” shares Hyatt.

Subsequently, Hyatt developed new techniques to allow the sounds to be heard, enlisting Sarah Davachi, Kelly Moran, Felicia Atkinson and more to rearrange the recordings for Ultrasonic.

Aiming to highlight the plight of the Indiana bat and its habitat, Ultrasonic features a printed booklet of The Endangered Species Act of 1973.

Jeremy Deller & Adrian Sherwood also sampled bat echolocation sounds on their collaborative Freetail Dub 12″, released via The Vinyl Factory.
