What a difference a year makes. In 2016, 21 Savage watched Rich Chigga in the viral video for “Dat $tick” and commented, "I don't know what the hell he was thinking. He's got a goddamn fanny pack on right there. Hell nah.” In 2017, he’s rapping all over Chigga’s new single, spitting: “Rich Chigga, 21 Savage, now it's O.D.” In line with his recent self-produced singles “Glow Like Dat” and “Chaos,” “Crisis” is another solid effort from Chigga, as he continues to prove he’s outgrown his meme origin story and has the talent to be taken seriously as a legitimate artist.—Eric Skelton
