Today at 3 p.m. at Harkness Chapel, the Cleveland Composers Guild celebrates the 25th anniversary of Creativity: Learning Through Experience. The project brings together performers aged 18 and under and professional composer-members of the Cleveland Composers Guild. Professional composers work with young musicians to write pieces specifically for the students to perform. They coach the students as well. Over the last 24 years, the event has premiered 296 compositions and 409 students have performed. Admission is a $20 suggested donation. A reception follows the concert. (Niesel)
