You probably know Gucci Mane as “that guy who got an ice cream cone tattooed on his face (BRRRRR)” or possibly “that guy who occasionally has a diamond-encrusted Bart Simpson medallion” or “didn’t that guy go to jail for a minute?” You’re on the right track, but you should also know him as a hilariously and awesomely mush-mouthed, slow-drawling rapper, one whose gummed-up, syrupy slow beats have helped inspire the current deplorable “trap” trend in productions well beyond the realms of hip hop. Live rap shows are always a bit of a gamble, and Gucci Mane doesn’t necessarily seem like the type to be overly concerned with punctuality or effortful showmanship, but I bet he still throws a good-kind-of-weird party.
