This exhibition at the National Hispanic Cultural Center will feature aural history unearthed as 29 new experimental works by composer and musician Marisa Demarco degrade. “The Mountains Wore Down To The Valleys” supports the intergenerational sharing of values and the erosion of trauma over time. Collaborator and fellow artist Adri De La Cruz will conduct interviews with her family members, from the oldest living relatives to the youngest. Their narration at the heart of this work will convey positive traits handed down through time. For the sound installation, the interviews are etched into a thick, archival vinyl record that plays on a record-player on repeat. Twenty-nine other, thinner, lathe-cut records featuring experimental compositions play, too, on individual records players through independent speakers. These thinner records will erode over the course of continual play for 24-72 hours, changing sonically until they are gone, and only the family voices remain.
