Our mission is to promote classical musical arts and education to ALL people, through an engaging and profound musical experience.
The Boulder Chamber Orchestra (BCO) was established in 2004, and stands as Boulder’s premier professional chamber orchestra. Since our formation, we have consistently played to sold-out audiences and featured some of the most sought-after musicians across the world. BCO is committed to playing under-performed, rarely-heard pieces to educate audiences and bring to light incredible composers.
