A choir scheduled to perform Saturday night at Carnegie Hall made the best of their canceled show amid a massive power outage that plunged a large chunk of Manhattan into darkness.

Author and professor Briallen Hopper tweeted that she was stuck on a train for nearly an hour before going above ground to find darkened restaurants and buildings. Hopper told INSIDER she was in the midst of forming a backup plan to catch a train when she followed what she described as a "celestial sound."

"All the trains at 63rd were down so I decided to walk to 57th to see if any trains were running there," Hopper said, referencing a station in the approximately 20-block radius that experienced outages. "Then I heard this celestial sound and I walked toward it."

I guess this is what they call a New York moment. After being trapped on the F for an hour because of the power outage I emerged to see dark restaurants & traffic lights, civilians directing traffic, & an evacuated Carnegie Hall concert happening in the street. #nyc #Blackout pic.twitter.com/3p9UWtRrel

One user said it was the Millennial Choirs & Orchestras, which was the group scheduled for an 8:30 p.m. show before the venue announced the evening's shows were canceled.
