In today’s Sound Perimeter, we listen to Arizona composer Kira Zeeman Rugen and her piece Atmosphere, and Mexican composer Juan Pablo Contreras with Mariachitlán, pieces about place, about what it means to arrive somewhere new, to carry the places we have known with us, and to slowly begin to feel connected to somewhere else.

In today’s Sound Perimeter, we reflected on saudade, that beautiful Brazilian word with no perfect translation through the music of Egberto Gismonti and Antônio Carlos Jobim, and the beautiful interpretations of the Bianca Gismonti Trio and Eliane Elias.

Today's Sound Perimeter explores Jupiter through music.

"Although the planet often evokes grandeur, today's musical journey was surprisingly intimate. Through the works of Wolfgang Amadeus Mozart and Mario Salvador, we heard music that was gracious and contemplative, with moments of quiet nostalgia and subtle emotional tension, offering, I hope, a quiet but meaningful pause in your day."

- Host, Lia Uribe

Featuring works from Mario Salvador and Klara Poznachowska.

Today's Sound Perimeter celebrates the Fourth of July through the music of two remarkable American women composers. Nkeiru Okoye's "Voices Shouting Out", written in the aftermath of September 11, reminded us that even in moments of profound loss, music can become a voice of resilience, hope and collective resolve. Jessie Montgomery's "Banner" invited us to hear our national anthem in a new way. Rather than treating "The Star-Spangled Banner" as a fixed symbol, she reimagines it as a living tradition, one that grows richer as it embraces the many cultures, histories, and voices that shape America. By weaving the anthem together with other musical traditions from across the Americas, Montgomery reminds us that our shared ideals are strengthened not by a single voice, but by many voices heard together.

Today's Sound Perimeter features two works by Canadian composers: "The Bessborough Hotel" by Nicole Lizée and "Pièce pour violon et clarinette" by Claude Vivier. While these pieces sound very different from one another, both composers invite us into imaginative and unexpected musical worlds.

Lizée draws on ghost stories, popular culture, and technology, while Vivier explores color, mystery and the expressive possibilities of sound itself. Together, they offer two distinct perspectives on Canadian contemporary music and remind us that music can tell stories, spark curiosity, and transport us somewhere new. Performances by Nicole Lizée and Ensemble Made in Canada.

Sound Perimeter from Lia Uribe is dedicated to unexpected voices in and around music. Today, we listen to the music of two contemporary composers: Clarice Assad and Gabriela Lena Frank, brought together under the idea of Heroines, women whose music moves fearlessly across cultures and traditions with imagination, honesty, and vitality.

Today's Sound Perimeter features "The Currents" by Sarah Kirkland Snider (performed by Irene Kim) and "Árbakkinn" by Ólafur Arnalds, two pieces connected by a sense of flow and quiet introspection. Both explore what moves beneath the surface, but in different ways: Snider through the intimacy of solo piano, Arnalds through a blend of acoustic sound and technology that feels more atmospheric and open.

Today's Sound Perimeter listens across distance: two composers, both born in 1946, two different worlds. Vladimir Martynov and Mary Lou Williams arrive at the sacred from very different paths. Martynov through stillness, through a sound that unfolds like breath, rooted in chant and contemplation. Williams through voice and rhythm, through jazz, blues, and gospel carried into a liturgical space.

Different languages, different histories, and yet, both works hold a quiet insistence on justice. On compassion, on the dignity of human life.They are not the same sound, but they shared gesture: music as reflection, as prayer, as a way of imagining something better.
