This sweetshop full of lollipops offers some favorites from the King’s Singers’ vast repertoire of melodious part songs, sung with their trademark lustrous tone and precise, yet unforced, clarity. Yearning songs of love and loss range from sixteenth century to today, with some particularly fine contemporary examples from Libby Larsen. Schubert, Schumann, Bairstow, Elgar and Saint-Saens are all represented, and who can resist the rich sonority of Arthur Sullivan’s “The Long Day Closes”?
