A performance by a North Korean band in honor of the country's recent rocket launch shows an epic, high-energy celebration of the accomplishment, to say the least.

The Moranbong Band performed in celebration of the Dec. 12 launch, which the communist country claims is a weather satellite.

The band performed an instrumental version of the song "Without a Break," which, according to the unofficial North Korea Military Choir Facebook page, celebrates the bravery and fortitude of the country's military.

About two minutes in, the audience claps as photos of Kim Jong Un are pictured behind the band, after which another slideshow of the actual rocket launch is displayed behind the musicians.

While the video isn't dated, the blog nkleadershipwatch posted a picture of Kim Jong Un and his wife as they "applaud during a performance by the Moranbong Band at a banquet celebrating the 12 December 2012 launch of the U’nha-3 rocket," which took place Dec. 21.

The U.S. suspects North Korea is testing its own rocket technology so that it might be able to attack other countries at some point in the future.
