Men’s Camerata president and founder Brad Spencer hosted the Camerata’s 30th anniversary season at his home Dec. 1. The group seeks to perform, promote and preserve the rich legacy of men’s choral music through a variety of initiatives. The past season was highlighted by three performances with the National Symphony Orchestra at the Kennedy Center Concert Hall of the rare Piano Concerto by Ferrucio Busoni, one of the largest works ever written in this genre in which a men’s chorus sings in the final movement.
