Today's Sound Perimeter features excerpts from "Nightscape" and "No-Man’s-Land Lullaby", both written by Jamaican composer Eleanor Alberga, works that linger at the edge of place and memory, where atmosphere gives way to deeper histories carried quietly in sound.

Pianist Gabriela Montero and salsa legend Willie Colón share a stage on Sound Perimeter — two artists from different worlds united by presence, improvisation, and music as a vehicle for truth.

Today's Sound Perimeter explores change, how it happens inside the music and around it. We begin with Philip Glass's Metamorphosis I, where repeating patterns shift so gradually you almost don't notice until the whole atmosphere feels different. Performed by pianist Lisa Moore. Then we turn to Terri Lyne Carrington and a spacious performance of her piece "Unconditional Love." Terri Lyne Carrington has carried her own kind of transformation by the way she leads offstage at the Berklee Institute of Jazz and Gender Justice, imagining a jazz world that's more inclusive and more equitable.

Today's Sound Perimeter spends time with two bassoon pieces that have stayed close to host Lia Uribe over the years. Music holding memory, shifting shape and meeting us differently each time we return to it. Past and present, coexisting.

Today's Sound Perimeter features two pieces of music, one by French composer Gabriel Fauré, and the other by American composer Meredith Monk.

Host Lia Uribe says, "I chose these works because, lately, I’ve been turning tomusic for solace as we move through this present moment. Not necessarily to understand it, maybe just to sit with it, to hold space.

"For me, these pieces create a shared space for feeling, for presence, reflection and care. A place to pause. Maybe it’s about still being able to recognize beauty, or about processing what we're carrying, or finding inspiration to center light rather than darkness. I’m not entirely sure. But I do know that this music offers a way to be with life and death, complexity and tenderness, that's it. I hope you connected with these works, and if you feel moved to do so, I'd love to hear what the music said to you. Reach me at soundperimeter@gmail.com."

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.
