Jaw-dropping footage emerged Sunday showing a giant tsunami wave sweeping away a boy band mid-performance in Indonesia.

Crowds can be seen in the shocking video swaying along to a beachside Saturday performance by the rock band Seventeen — seconds before the natural disaster hits, engulfing the stage.

Loud shrieks can be heard before the 11-second video ends.

The band confirmed that bassist M Awal Purbani, guitarist Herman Sikumbang and road manager Oki Wijaya were dead.

“The water washed away the stage … and dragged away everyone at the location,” the statement said.

Two other musicians, a crew member and the wife of the band’s frontman are still missing.

“Please pray that we can find Andi, Herman and Ujang and my wife,” the lead singer, Riefian Fajarsyah, said in a tearful Instagram video.

Fajarsyah also posted a heartbreaking photo Sunday showing him and his wife, Dylan Sahara, kissing in front of the Eiffel Tower, with the caption: “Today is your birthday… hurry home dear.”

A tsunami hit the Sunda Strait on Saturday, triggered by an underwater landslide caused by the eruption of the Anak Krakatau volcano. At least 222 people are dead with 745 still missing, officials said Sunday.

Coastal residents reported not seeing or feeling any warning signs — such as an earthquake — before nearly 10-foot-high waves washed ashore.

Some 200 employees of the state utility company PLN had been at the concert on Tanjung Lesung beach for their end-of-year party.

“We were shocked because a lot of the people who went there took their families,” said Yulia Dian, a manager for the band in Jakarta.

PLN said 29 of their workers were among the dead and 13 were missing.

“They’d been sharing stories, they were having fun at the beach,” Dian said. “We didn’t expect this.”
