Pro Musica Joplin presents New York Polyphony in concert Thursday December 5 at 7:00pm at Central Christian Center, 415 S. Main Street in Joplin. This all-male vocal quartet is recognized as one of the finest vocal ensembles active today, applying a refreshingly modern touch to repertoire that ranges from austere medieval melodies to cutting-edge contemporary works. Their program in Joplin will be themed for the Christmas season and titled "Wondrous Birth, O Wondrous Child." It will last just over an hour with no intermission; it's free and open to the public, but donations are appreciated. For more information call Pro Musica Joplin at (417) 625-1822, or visit www.promusicajoplin.org.
