Engaging diverse communities through innovative programming, education, and outreach. 

About Sphere Ensemble

Sphere Ensemble was formed in 2011 by professional string players driven to explore the vast potential of the string ensemble.  Moving beyond the stereotype of classical music tradition, Sphere’s programs include both the masterpieces of string orchestra repertoire and exceptional works drawn from all genres to create a new definition of modern performance.  Innovative arrangements are written by group members generating a unique and transformative musical experience.  Sphere’s debut album, Divergence, was named one of Colorado Public Radio’s Top 20 classical album releases of 2015.  
Sphere Ensemble has new leadership and a new vision with Executive Director and Artistic Co-Director Alex Vittal, longtime viola player and arranger in the group.  Alex seeks to expand the reach of Sphere Ensemble in Front Range communities by bringing performances and educational programming to marginalized audiences including: Title I schools and communities, homeless shelters, juvenile detention centers, women’s shelters, children’s hospitals, and assisted living and memory care facilities.  
He is joined by Alejandro Gómez Guillén, highly acclaimed violinist, conductor, and musical director, as Co-Artistic Director of Sphere Ensemble. Alejandro is currently the Associate Conductor of the Fort Worth Symphony, Artistic Director and conductor of the Bloomington Symphony Orchestra in Indiana, and he is also a Freeman Conducting Fellow with the Chicago Sinfonietta.  Alex, Alejandro, and Sphere are excited to collaborate to create Sphere’s signature brand of music.
