The students will attend workshops and rehearsals throughout the day, and receive additional instructions from Central College faculty members. The day will culminate with an evening concert in Douwstra Auditorium featuring the “Singfest” participants and Festival Choir with the Central College A Capella Choir. The 7:00 p.m. performance is free and open to the public.
