DJs Sara and Ryusei are in single digits yet they appear to be pretty nonchalant about their wicked scratching talent. I wonder if their parents cracked the whip on 'em or if they practiced that much of their own accord. Skills like the ones they're flaunting here require serious lab time. I'm going to guess it's the latter.
Anyway, check this out and take care not to fracture your mandible on the desk/table.
