FARMINGTON — On Saturday, June 25, the international, award-winning men’s choral group Mastersingers USA will perform at Nordica Auditorium.

The chorus of more than 90 men, whose repertoire is widely varied, challenging and mostly a cappella, will sing sacred and secular music, folksongs, spirituals and contemporary music spanning 500 years.

They sing works by masters of polyphony such as Josquin, deKerle, Palestrina, Vittoria, Gallus, Allegri and Lotti, as well as 20th century compositions by Bedard, Biebl, Clausen, Heath, Mawby, Theimer and Thompson. Their programs also include works by Schubert, Bruckner, Gounod, Kedrov and Tchaikovsky.

The men in Mastersingers USA have achieved and sustained the highest professional standards under the leadership of founder and music director Bruce G. McInnes, adjunct professor of music at the University of Maine at Farmington.

They are selected based on the extent of their musical and singing experience, and on the timbre and quality of their voice.

The chorus has performed in some of the world’s greatest cathedrals, at major festivals, in small village churches, concert halls and amphitheaters, and on street corners as the spirit moves them.

Members of Mastersingers USA, who range in age from 18 to 75, come from all over the United States, reuniting once a year in a different part of the country to rehearse and perform. Every third year, they go on an international tour.

The Mastersingers won first place in the prestigious International Musical Eisteddfod in Llangollen, North Wales, in 2003, and again in 2005 when the group represented the United States at the First International Congress of Men’s Choirs in Barcelona.

While on tour in 2010, the ensemble performed in Estonia, Latvia, Lithuania and St. Petersburg, Russia.

The concert will begin at 7:30 p.m. Tickets are $15, $5 for children under 16. For tickets, email aiwmtickets@yahoo.com. Nordica Auditorium is on the University of Maine at Farmington campus. For more information on Mastersingers USA, visit www.mastersingersusa.org.
