Charles Moe, Artistic Director, East Central Minnesota Chorale

The East Central Minnesota Chorale (ECMC) is a civic choir representing the five county area of East Central Minnesota. The ensemble was founded and led by David Clarke, former director of choirs at Cambridge High School, in 1981. The Chorale has been privileged to have many accomplished directors over the years, Dr. Dennis Port (Bethel University Choir, retired), Dr. Mark Potvin (Luther College), Joseph Osowski (St. Michael-Albertville HS), and most recently, Charles Moe (Princeton HS). In 2010 the Chorale expanded to include Unum Vox, a high school honors choir from the five county area high schools. UV was founded and led by Dr. Mark Potvin and has had only two directors since its inception, Mark and Tonya Barnes. ECMC has performed in a variety of locations across East Central Minnesota, the Twin Cities, and other locations across the state. The Chorale has been selected twice to perform at the Minnesota State Convention of the American Choral Directors Association. A conscious effort is made to include music from a variety of eras, cultures, and genres. The Scholarship Concert raises money to present scholarships to graduating high school seniors who plan to continue singing at the college level.​​

Unum Vox

In spring of 2010, ECMC applied for and received one of the inaugural Arts and Cultural Heritage ("Legacy") grants to form Unum Vox, a regional honor choir for students in schools that service Chisago, Isanti, Kanabec, Mille Lacs, and Pine counties.  Unum Vox (translated as "one Voice" and pronounced "oonoom vocks") is an elite choir designed to enrich the typical high school choir experience by allowing students  from various schools to excel in a common pursuit of quality singing.  The hope of the East Central Minnesota Chorale is to solicit the participation of serious 10-12 grade choral students from area schools to sing in an ensemble whose artistic capabilities cater to their desire to perform at the highest level possible.  Unum Vox engages singers in conversations about choral literature,  teaches healthy singing, and introduces students to music from a diverse set of world cultures.  Student singers take the skills and experiences from weekly rehearsals home to share with their peers in the hopes of enhancing their leadership in their high school ensembles.
