NYC’s Unheard-of Ensemble Joins Local Composer Pamela Martinez & Germany's PART Musik for Free San Antonio Sound Series at Confluence Park

Set at the confluence of the San Antonio River and San Pedro Creek, the performance reimagines the river as a living musical score, full of memory, sound, and flow. The concert is the culminating event of the Collaborative Composition Initiative (CCI), a national workshop hosted by New York-based Unheard-of Ensemble, in partnership with San Antonio composer and artist Pamela Martinez / Teletextile.

This performance marks the final event of CCI in San Antonio, celebrating a series that has transformed the San Antonio River into a space for deep listening and creative reflection. Thirteen composers, assembled from across the world, will present new works developed during an immersive, weeklong residency along the San Antonio River system. These site-inspired compositions reflect their personal engagement with the river’s soundscape, ecology, and cultural landscape, offering the public a singular evening of experimental music to inspire reflection on the region's Indigenous roots, environmental resilience, and restoration efforts.

Drawing on field recordings, poetry prompts, and natural soundscapes, the composers have created new works for chamber ensemble and electronics. The concert will feature performances by:

Unheard-of Ensemble (NYC)
A boundary-pushing chamber quartet from New York City, Unheard-of Ensemble is known for innovative programming that blends classical instrumentation with electronics and interdisciplinary storytelling.

Based in Essen, Germany, PART Musik is an experimental collective working at the intersection of composition, performance, and improvisation. Their performances often combine live electronics, early instruments, and contemporary dance.

Audiences can expect a range of experimental styles from acoustic chamber music to immersive multimedia works, designed to echo the rhythms and resilience of the river itself.  The audience will move through the park to hear music performed at different site-specific locations for the opportunity to enjoy a summer night of sound, story, and environmental reflection.

This unique outdoor concert is free and open to the public, with seating on a first-come basis. To help organizers plan for the evening, attendees are encouraged to RSVP in advance. Secure your spot and receive event updates by visiting the official Eventbrite page here.
