TWR is a Christian media organization that broadcasts biblically based programs in more than 230 languages and dialects to people in more than 160 countries. David Hartman, the original host of ABC’s “Good Morning America” and current host of North Carolina Symphony radio broadcasts, will present the broadcast to listeners. Instructions for listening to the concert are available at: http://www.twr360.org/listen-live.“In his ‘Messiah,’ Handel creates musical settings of Old and New Testament Scripture to present the drama of Jesus’ saving role in the world,” said Rodney Wynkoop, director of Chapel Music and conductor of the Duke Chapel Choir. “TWR is giving us the opportunity to present this compelling composition to an international audience.”“Transmitting a live, multinational concert of this kind represents the perfect opportunity to commemorate our organization’s 60th anniversary, while offering praise to God and a special gift to its diverse audience of listeners,” said Lauren Libby, president and CEO of TWR. The Chapel Choir performance of the piece features a professional orchestra and soloists. Including two intermissions, the concert lasts about two hours and 45 minutes.
