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.

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.
