K-pop people: What's happening in this DJ DOC video? They're obviously parodying a whole bunch of popular Korean groups, but I'm hardly one to understand the nuances, or even the broad sweeps; 'cept obviously at one point they're doing a goof on After School's "Bang!," which is my Korean track of the year, though this DJ DOC one - "I'm A Guy Like This" - is pretty damn good itself, and shows a pronounced Cuban/Cuban American tinge. According to kpoplive.com, also being ribbed here are Lee Hyori, CN Blue, and Big Bang, the last two I don't know anything about.

"DJDOC나이런사람이야 뮤직비디오" (Watch on YouTube)

And what's happening in this stage presentation, with the dancing girls and the (I assume) traditionalist instrument?

[YouTube killed the vid.]

Also, a discussion of the significance of DJ DOC would help, as I gather they were important in the Korean hip-hop '90s, their new record being their first in seven years.

I enjoy this new YDG single quite a lot. His style lies somewhere between Waka Flocka and Soulja Boy - so much suppressed energy that he only knows to let it out through grunts and mumbles.

The live performances of this are a sight to behold, the way he hides behind his cap http://www.youtube.com/watch?v=BKwd9rYuoZ0

Wow. Don't know what I think about the vocals. They're almost hypothetical, unrealized. Don't think I've heard anything like it. His movements are impressive, as you say, somewhere between suppressed and released.
