For more than a century, the St. Olaf Choir, conducted by Dr. Anton Armstrong, has set the gold standard for choral singing, performing for millions around the world. Composed of 75 mixed voices, the St. Olaf Choir is hailed as one of the nation’s premier a cappella ensembles, renowned for its artistry and beauty of sound.  The St. Olaf Choir was founded in 1912 by F. Melius Christiansen, whose work established the ensemble’s standard of excellence and its tradition of bringing music to audiences outside of campus. Christiansen chose spiritually profound music and pushed student musicians to perfect a tone that was disciplined, controlled, and free of excessive vibrato. That sound — securely in tune, controlled in pitch, smooth in delivery — became the choir’s hallmark. When Armstrong took the helm in 1990, his vast knowledge of music and his ability to articulate a vision to singers and audiences alike took the St. Olaf Choir to the next level, adding more flavor to its signature sound and further expanding its repertoire to include music of the Pacific Rim, Africa, and Latin America. Under Armstrong’s leadership, the choir continues to expand its touring horizons, engaging capacity audiences in major concert halls throughout the United States and worldwide. The ensemble has toured internationally 16 times. Most recently the St. Olaf Choir toured South Africa for three weeks in 2024, performing alongside Tuks Camerata, Quava Vocal Group, and other standout choral ensembles.
