History of the Moranbong Band
The Moranbong Band, also known as the Moran Hill Orchestra, was formed in 2012 by DPRK leader Kim Jong Un, thus smashing the myth that people cannot listen to music in North Korea.
Through the years 2012 – 2016, the Moranbong Band was a staple of North Korean life frequently performing to mark significant national events and holidays.
Since 2016 the band has appeared less often but still makes the occasional performance usually alongside other DPRK Bands.

Contrary to many people’s popular belief, the Moranbong Band has seen many members come and out over the years. Some have disappeared from the band temporarily while others have left only to re-emerge elsewhere, usually with a different music group.

Most members of the Moranbong Band are graduates from either the Pyongyang University of Music or Goldstar Academy in Pyongyang.

We have compiled a list of Published Moranbong Band Performances below. Published meaning these concerts were filmed and aired on North Korean state media at some point.

How to see the Moranbong Band?
Your best chance to see the Moranbong Band perform is on our annual New Year’s tour or our New Year’s Ultra Budget tour.
Occasionally in the past, chances have come up while on tour to attend a concert. However, this is almost impossible to predict in advance, as tourist eligibility to participate is only usually announced a day or two before the concert.
And as for the future of the Moranbong Band? Well alas the country still remains closed right now, so who knows maybe they have broken up, or gotten solo deals? We certainly hope not, and will certainly be heading their way if the country does reopen.
