Japanese translation is by Matsui Sei’ichiro (松井聖一郎).
Cho deals mostly with Kim Jong-il’s art theories and descriptions of the band’s songs, but he also gives a few small pieces of new information.
The location in the centre and front probably has a meaning.
In such a location you can closely watch the stage behavior of established stars.
We also have other evidence of the timing of the establishment.
Kwaximus, and a bit later Umutcan Dogan、 found that several members of MB were in the audience of an Unhasu Orchestra concert in 8 March 2012, X3HOzmc.
She was pregnant at the time, and apparently gave birth between this date and the first MB performance in 6 July 2012.
They thus can surmised to be highly talented musicians, who have a good education, and can move easily between classical and North Korean popular musical genres.
There are also other shots scattered throughout the concert, where one or two of the ladies can be seen a bit more clearly.
Anyway, we have here at least 5 or 6 MB members in the same row, both musicians and singers, watching the performance of the current national top ensemble.
As they were sitting in the centre in the second row, they appear in the camera fairly often, but as they were not yet the main object of vision, there never were any close ups. From the left we have Kim Hyang-sun (grey), Kim Sol-mi (white), Pak Mi-kyong (red) and probably Pak Son-hyang (blue).
The woman in brown dress cannot be identified at all.
