Colorado High School All State Choir Concert Tickets

The Colorado High School All State Choir Concert (COASC) brings together three exceptional ensembles—the Treble Choir, Mixed Choir, and Tenor/Bass Choir—for a premier statewide celebration of young vocal talent. Organized in coordination with state music associations like CHSAA and CMEA, COASC stages a professional-quality festival experience that showcases the best high school singers from across Colorado. Performances are typically held at Denver’s Buell Theatre, with pre-festival rehearsals conducted at nearby hotels such as Embassy Suites. Auditions determine participation, and the festival serves as a collaborative platform for aspiring singers to learn, perform, and connect with peers and educators in a supportive environment.

For families, students, and supporters, COASC provides an accessible, well-organized experience with ticketing through AXS and livestream options via Persuasion Sound, ensuring fans can enjoy the performance whether they’re in the venue or watching from home.
