Everyone is raving over Jay Park's crisp choreography for his comeback track, "Abandoned". While we certainly got a good view of it through his music video and numerous stage performances, this just-released practice video really spotlights the skill required to deliver such complicated moves.

Check out their flawless performance below! Tip: numeroix
