Who are we? SoundProof origins and artistic focus )

Formed in 2009, SoundProof is an extensible performance trio with Patricia Strange (violin), Stephen Ruppenthal (trumpet, flugelhorn, text-sound composer), and Brian Belet (viola, bass, & Kyma processing). The ensemble's mission is to explore the creative and interactive potential in the convergence of sound, music, performance, and technology. Drawing from the wealth of late 20th-century and current 21st-century sources, SoundProof events realize new possibilities for sound and music, blending the traditions of contemporary performance with the exigencies of real-time digital processing.

Rehearsing at KISS 2015

Patricia Strange has been at the leading edge and creative forefront of contemporary violin performance for many decades. Her playing and interpretations have continually re-defined the musical possibilities of extended violin performance techniques. Along with her late husband, Allen Strange, she co-authored the book The Contemporary Violin; Extended Performance Techniques, published by Scarecrow Press in 2001. She co-founded two live electronic music ensembles, BIOME and The Electric Weasel Ensemble which toured the USA, Canada, Mexico and Europe. She currently lives on Bainbridge Island, WA where she continues to perform and teach.

Composer/performer Stephen Ruppenthal is Principal Trumpet and Contemporary Music Advisor for Redwood Symphony. Stephen has been Guest Artist-in-Residence at numerous universities in the US, and taught Electronic Music Studio Arts and Composition at the Center for Experimental and Interdisciplinary Art (SFSU). Stephen was a founding member of the Electric Weasel Ensemble, and appeared with EWE and other groups in the USA and abroad, including “President’s Breakfast” at the New Music Festival. Stephen is also known for his performances and writings on text-sound composition.  Stephen is currently recording a collection of new trumpet and electro-acoustic commissions by Larry Austin, Brian Belet, Elainie Lillios, Allen Strange, and Dan Wyman. He performed Strange’s Velocity Studies V: NGate for the SEAMUS Electro-Acoustic Music Festival (included on New Music from SEAMUS, Volume 18), and performed Belet’s System of Shadows for trumpet and Kyma at EMM 2008, SEAMUS 2009, ICMC 2010, and the 2010 Kyma International Symbolic Sound Conference (Vienna). In addition, Stephen premiered Elainie Lillios’ November Twilight at numerous venues including the 2012 ICMC Conference in Ljubljana, Slovenia.​

​I enjoyed the concert [at EMM]. It provided a nice variety of material and was expertly performed. Your spoken word piece was very interesting. I was intrigued by how manipulating the controllers impacted the piece. (2012)
