It’s optional and the student performers sign-up (or are recruited). Additional information on the evening is provided below from Mr. Bishop: “North Music Showcase is being put on by the Tri-M students. The concert will primarily feature student-run performance groups from all three performing ensembles at CRN (Band, Choir, and Orchestra). Admission to the concert is free, but the Tri-M students will have an optional donation basket set up for the Save the Music Foundation, an organization whose mission is to help students, schools, and communities reach their full potential through the power of making music.”
