GROTON — The award-winning Groton-Dunstable Regional High School Chamber Choir returned recently from New York City, where they joined with about 200 other singers from around the world to perform the music of renowned composer Eric Whitacre, under Whitacre’s direction. The concert, held April 8 at Carnegie Hall, was sold out, with an audience of about 2,800.

The Chamber Choir, which is led by Music Director Timothy Savoy, was selected for this honor because of the quality and high level of musicianship demonstrated by the singers through their audition recording.

The singers spent five days and four nights in New York City in preparation for their concert, with about 9-10 hours in rehearsal. They also had the opportunity to take in history and culture in New York City.

The Carnegie Hall performance is the latest honor for this elite high school choir. Last year, the group was invited and traveled to Italy and Croatia for a series of performances and exchange concerts. They completed a similar singing tour of Italy, Austria, and the Czech Republic in 2014. And, in 2012, the group won the honor of performing at the 2012 Summer Olympics in London, England.
