Rockumentary Turn It Up To 11 (반드시 크게 들을 것) got a DVD release on March 15. Unfortunately there is only Korean subtitles, but I have a feeling it might make for good entertainment anyway as it follows punkabilly band Galaxy Express and the now defunct Tobacco Juice. Also seen in the movie are Apollo 18, The Black Skirts, and The Moonshiners.
If you have access to DramaFever you can stream the movie with English subtitles before deciding whether to pick up the DVD or not.
