Sounds of the Unborn

Sounds of the Unborn is an experimental music album produced by Elizabeth Hart and Iván Diaz Mathé based on recordings of their then-unborn daughter Luca Yupanqui, released by Sacred Bones Records on April 2, 2021. The couple recorded Luca during her mother's third trimester of pregnancy using MIDI biosonic technology to pick up electromagnetic impulses and translate it into digital sound which was then manipulated by synthesizers played by Diaz Mathé. A remix album called Conversations was released September 9, 2022, with contributors including Suzanne Ciani, Peaking Lights, Dean Hurley, and Laraaji.
