The 10 000 People Strong Grand Art Performance Celebrating the 70th Anniversary of the Workers' Party of Korea "Great Party, Rosy Korea" () was a one-off artistic performance held on the 11th of October 2015 in celebration of the 70th anniversary of the ruling Workers' Party of Korea. The performance was originally meant to be hosted on the evening of the 10th of October, however, this was moved back a day due to wet weather.
The performance was held on a large floating stage in the middle of the Taedong River with the Tower of the Juche Idea as its backdrop. The audience was seating along the steps of the river as well as on seating in Kim Il Sung Square. The large stage was decorated with a large red flag baring the hammer, sickle and writing brush of the Workers' Party as well as a large LED display. On ether side of the stage, multi-colour dancing fountains
The show was directed by People's Artiste Ryang Chang-nam () and was produced by O Yongchà Âl (), O Hungchà Âl () and Ri Yunho (). The business team consisted of Department Director at the Ministry of Culture Kwon Hyok-bong (), Kim Haksun () and Peoples' Artist Ryang Changnam ().
The performance was divided into two sections, with a total duration of over 3 hours.
The performance "Great Party, Rosy Korea" was attended by the then President of the Presidium of the Supreme People's Assembly Kim Yong-nam () and the then Premier Pak Pong-ju (), as well as key Party and state leaders. In addition to this, many delegations from various countries, foreign ministers from international organisations and foundations, foreign ambassadors and foreign guests were all invited to the performance along with members from the General Association of Korean Residents in Japan (the Chongryon) () and the chief of the Pyongyang mission of the Anti-Imperialist National Democratic Front.
The performance was broadcast on the state television station Korean Central Television a week or so after the performance. The reason for this delay was most likely the fact that the concert was never carried live to TV, but, instead was edited from multiple recordings of the concert including the rehearsal and debut. Unlike the DVD version, the television broadcast was instead split into two distinct sections; separated by a question and answer segment with those who recollect memories of the history of the Party. This Q&A was hosted by narrator Kim Jong Il Prize Laureate People's Actress Paek Sung Ran () and was most likely held during the intermission period. Following this, the interviewees perform a song.
