In an era of Columbine-type disasters at our schools, Triangle residents should be grateful for the 16 years of violence prevention work by the Center for Peace Education, which was started by a group of teachers who realized that no one was training them to successfully resolve conflict in classrooms. This Sunday, Sept. 17, the Center celebrates its anniversary with Concert for Peace 2000. The show will include orchestral and choral performances by members of the Chamber Orchestra of the Triangle and other local orchestras, as well as youth musicians from around the Triangle. Lorenzo Muti conducts a performance of Aaron Copland's "Fanfare for the Common Man" and "A Lincoln Portrait," which will be narrated by historian John Hope Franklin. In an ironic twist, the set list also has the Durham School of the Arts chorus and the NCCU chorus belting out "Battle Hymn of the Republic." This is a worthy cause, so tickets are steep: $50 reserved, $20 general admission, $10 students and free for youth 16 and under. For more information, call 929-9821.
