I'm sure you've found out by now, but there are several good websites from or associated with the DPRK. www.naenara.com.kp/en/ exploredprk.com/ uriminzokkiri.com/ arirangmeari.com/ www.korea-dpr.com/ Some are quite slow and others just in Korean but Google Translate is just about good enough. There is lots of music, videos, pictures and articles. Not sure if they have the pictures from this video though haha - but they probably do somewhere. And DPRK music is awesome - its been my favourite genre for almost 2 years now.
