The singer was nearing the end of a private show in front of a packed house when the power for most of the stage instruments suddenly went out, said his manager, Scooter Braun.
"Then we hear the fire alarm," Braun said by phone Monday evening. "Literally, the boy blew up the Apollo -- he heated up the Apollo."
But Bieber still managed to finish his show, with the help of fans singing along with him.
"What it turned into was an Apollo moment, like one of those impromptu things," said Nina Flowers, the Apollo's rep.
"It was one of the most special nights I have ever been a part of," said Braun.
The power outage, which only affected the stage instruments and some lighting, occurred toward the end of the show. Braun said they were told the problem was supposed to be only a few minutes, but it stretched to more than 40 minutes.
At first, Bieber took the outage in stride.
"He was joking, he said it was all the hot girls in here," Flowers said.
He then got on the drums, which were working, for a solo, and had the crowd serenade Braun for his birthday.
Then Bieber put his energy into performing for his fans, who stayed in the audience during the delay.
"He walks out, he literally quiets the crowd, and he says, 'I'm sorry the power is out. [But] you guys have always had my back. I'm going to sing 'Boyfriend' and you're going to sing it back to me.' "
