The “Mirage” Advanced Women’s Chorus at Mount Vernon High School was in rehearsal on Tuesday, March 6, for this Thursday night’s “I Hear A Voice” Festival Concert in the Mount Vernon High School Little Theatre.

In addition to the advanced women’s chorus, “Measure for Measure” Madrigals, “Montage” Concert Choir and Guitar IVIII will perform. Thursday’s 7 p.m. concert will be different from any other, as applause is not allowed until the three choruses have performed their three pieces and the entire concert is finished.

Mount Vernon High School Director of Choirs and Guitar Studies Judith A. Belzer is attempting to duplicate the intensity that the students will experience on Saturday, March 10, when they perform in front of judges for their choral assessment — equivalent to a choral Standard of Learning.
