23 year-old ATL rapper Key! keeps it moving with this thumper of a song, “Tighten Up,” featuring Wavy Wallace. With some subliminal messaging via gameplay shots from Mortal Kombat, the video truly adds another dimension to the song. Key!’s deadpan facial expression ties the whole concept together, making the viewer feel as if they’re being bullied by the artist. He means bidness. Check it out and let us know what you think!
