On Monday, May 13, at 7 p.m., the Camden Hills Regional High School choral ensembles will present their annual Spring Concert in Strom Auditorium. Admission is free, with donations toward the 2020 Chamber Singer Festival trip accepted. The concert is under the direction of Kimberly Murphy, accompanied by Matt Mainster and assisted by student teachers Saphrona Stetson and Eben Wight. Pre-show music, at 6:30 p.m., will be provided by the student ensemble The Extension Chords (Myles Kelley, piano; Katherine Bowen, bass; Owen Markowitz, drums) playing a variety of jazz classics. They will also accompany the CHRHS Chorale on the first number, “Like a Mighty Stream.” The Chorale will round out their portion of the concert with “Give Us Hope” by James Papoulis, for which they will be joined by approximately 50 young singers (fourth- to sixth- graders) from the five-town area. Following the Chorale, the Treble Choir and Chamber Singers will present a selection of works ranging from spirituals and folk songs to classic sacred settings and contemporary Broadway songs. The Chamber Singers will also perform the three selections that recently garnered them a “Superior with Distinction” award at the Maine ACDA adjudicated festival in April. The student-led a cappella ensembles The Off Beats and Fortissima will present two selections, and the Chorale will return to the stage to honor District III and All State singers with a Mac Huff arrangement of “A Million Dreams.” The concert will end with McClure’s Caribbean-themed “Kyrie,” accompanied by steel drums and percussion
