The enthusiastic, staccato flow of Atlanta rapper Rich The Kid emerged as part of the Quality Control empire of trap music, as he put “the world on the wave” with his solo mixtapes and four volumes of Streets on Lock collaborations with Migos. Rich’s collection of QC tapes featured his high-octane shout next to collaborators like Gucci Mane, YG, Kodak Black, and Young Thug. Upon moving to Interscope in 2017, he saw his hustler tales break wide thanks to the Kendrick Lamar-assisted “New Freezer” and the brisk, bleeping single “Plug Walk.” In an era of narcoleptic rap songs, Rich’s voice proved to be a jolt of energy.
