The New York City Opera singers are warming up in preparation to entertain audiences at the Sacred Heart University Community Theater.

It’s their first time performing in Fairfield. The singers will be performing an hourlong holiday-themed piece titled "All is Calm: The Christmas Truce of 1914."

It portrays a moment in World War I when troops dropped their weapons to celebrate the holiday through song.

The hope is that this show, that combines classical singing theater and holiday music, will inspire the next generation of opera fans.

"It's historical, but it's lighthearted at moments, it's tender at other moments, and it's something children can absorb in a time frame of a little more than an hour and they won't be bored," said Michael Capasso, from the New York City Opera.

The show opens Wednesday night.
