“We recorded the entire track with non-electric acoustic sounds, using earthly materials that we made ourselves. We used a machine that plucks three combs, the delfín-bañera, a metal barred instrument (played with a violin bow or as percussion) and another machine that hits coiled springs. Finally we added a friendly message in a human voice encoded in the language of a new-born child (0 years, -25 years of Sónar’s age).”
