“Better recognize now, it’s an Emergency.”—at least, it is if you’re a wack emcee. When an up-and-comer who’s hardly cracked the latter half of his teens comes with a record as lyrically crushing as 15-year-old spitter Gameboi‘s latest mixtape leak, lackluster mic-rockers have good reason to fear for their future in the game. This gritty selection finds fellow Booth regular J57 taking control on the production tip. Over the Brown Bag All-Star‘s dusty breakbeat and 8-bit synth loops, the artist fires off some of his most jaw-dropping bars to date, exhibiting unflappable confidence along with a wide-ranging knowledge of popular music: “Ever noticed how I kill it on every song? / Check the epilogue; I’m a Foo Fighter in Everlong / I’ve got a Funkadelic flow, I call it Maggot Brain / I’m packin’ pain that make you never ever wanna rap again.” Proof that the Ann Arbor hopeful can go toe-to-toe with the game’s most talented rhymesayers, Emergency is sure to leave fans amped for the dopeness that awaits on Gameboi’s next street album, Young & Restless, due out in March. In the meantime, why not check out his Booth-hosted debut project, the Freshman of the Year EP?
