Today's Sound Perimeter features Metacosmos by Anna Thorvaldsdóttir, a contemporary piece inspired by the idea of crossing into unfamiliar territory, taking listeners inside a universe where forces are felt more than explained. We then turn to Venus, the Bringer of Peace from The Planets by Gustav Holst, where the cosmos becomes a place of reflection rather than fear, imagining Venus as a planet in a state of calm within a vast and mysterious universe.

Today's Sound Perimeter listens to two different versions of “Motherless Child”, one by Jubilant Sykes, and the other by Cécile McLorin Salvant. Each rendition holds the same spiritual at its center, yet each opens a distinct emotional world. Sykes offers the song with warmth, grace, and a sense of outward offering, shaped by movement, conversation, and color. Salvant, in contrast, brings an intimate, prayer-like reading, transparent, inward, and quietly intense.Together, these performances reveal the many lives a single song can live.

Today's Sound Perimeter explores two very different meditations on stillness and motion. Arvo Pärt’s Fratres, performed by Anne Akiko Meyers and Akira Eguchi, takes us into a space of quiet tension and spacious introspection, where repetition becomes a form of listening. And Hiromi Uehara’s Green Tea Farm, from a 2006 solo performance, offers another kind of reflection, rooted perhaps in memory or maybe in a personal sense of landscape.

Sound Perimeter is a segment hosted by Lia Uribe (@Lia Uribe) and dedicated to unexpected voices in and around music. We hope it’ll expand your knowledge and connection to sound and let music infiltrate your lives and transform your realities.
