OG Maco, the 22-year-old screamo-rap firebrand, bursts into Atlanta's Quality Control studios exactly how you'd hope, a bare-chested, heavily tattooed whoosh of energy, offering a huge high-five to fellow QC signee Skippa Da Flippa.
"Let me put my shirt on, so you know I'm in professional [mode]," he says.
He pops on a black shirt, but he is probably more recognizable shirtless. In his video for "U Guessed It," Maco plays the kinetic, spasmodic ringleader of an a impromptu moshpit held in a hotel elevator. The clip is currently at more than 10 million YouTube views, the single is riding up and down the lower reaches of the Hot 100 and Vine has made it a go-to anthem for six-second parodies (his favorite is "Hump Day Camel").
