Jay Park recently completed the first stop of his worldwide fan meets not too long ago, and it was during the Seoul fan meets where he revealed for the first time, 'Demon', an OST track for the movie 'Hype Nation', produced by the famous Teddy Riley. It won't be too long now until the official track and MV drops, but thankfully for all the Jaywalkers out there, Jay's B-boy crew�Art of Movement recently uploaded a teaser of the music video, albeit unfinished, onto their official Youtube channel. The teaser is only four seconds long, but hopefully these four precious seconds will leave his fans' mouths watering and screaming for more. Check out the (unfinished) teaser below! Also, a fancam of Jay's 'Demon' performance was recorded during Jay's Seoul fan meet. http://www.youtube.com/watch?v=52vVVM56YZI Many thanks to SKiLLY and lyndah for the tips.
