The Humboldt State University Singers (directed by Harley Muilenburg) capture the holiday spirit with Benjamin Britten’s “Ceremony of Carols,” and two movements of Randall Thompson’s “Testament of Freedom.” The Humboldt Chorale (directed by Carol Ryder) sings a Magnificat by Latvian composer Imant Raminsh, featuring solos by Fiona Ryder and James Gadd.
