Excalibur is an elite, mixed jazz choir consisting of upper classmen. They cover a variety of styles including jazz, pop, and musical theatre, and incorporate occasional choreography. This is an auditioned choir which has many extracurricular expectations in addition to the traditional choir concerts. This group is expected to perform in annual Pop Show and competes in the CHSAA and Greeley Jazz Festivals. Members of Excalibur are required to attend two morning sectionals and must be registered for a traditional choir.
