The album was recorded when the infant was still in the womb of her mother, Elizabeth Hart, bassist with the experimental rock band, Psychic IIIs.

Elizabeth Hart and her partner, Iván Diaz Mathé recorded “Sounds of the Unborn” in utero using electrodes placed on the bassist’s abdomen and “biosonic MIDI technology.”

This ultrasound system recorded the vibrations emitted by Luca Yupanqui in the womb and transcribed them into synthesizers. The meditative process took several hour-long sessions to achieve.

The recordings were then edited by Elizabeth Hart and Iván Diaz Mathé, who tried to intervene as little as possible to allow the child’s “message to exist in its raw form.”

“At a certain point the questions turned into, What would [Luca] say if she could speak? How would she react to the outer world? And ultimately, What kind of music would she play if she was able to?

This album is an attempt to answer those questions,” reads the press release for “Sounds of the Unborn.”

While the full album is slated for release in April, Sacred Bones has already shared the track “V4.3 pt.2.”

It is accompanied by a conceptual video designed by Elizabeth Hart and Iván Diaz Mathé, with the help of the American artist, Victoria Keddie. And, according to Sacred Bones, Luca Yupanqui is already a fan.

“Her awareness of what was happening was astounding,” the label states, recalling her parents mixing the album in 2020.

“She would open her eyes wide and stare at her parents, seemingly recognising her own sounds from the womb, knowing that they were revisiting those rituals that made them come together as one.”
