Detroit’s Payroll Giovanni has a smooth and buttery voice, tense in rhythm but conversational in tone. He sounds like he’s entering a party while rubbing the sleep out of his eyes, and he's comfortable sliding in gracefully over big sounds with lots of echo and space. These are all classical West Coast-rapper traits, and Giovanni’s vocal tone is oddly redolent of Too $hort, if he were rapping on muscle relaxants. “Big Bossing” is a spotless car-rap song, its backing track a clean mixture of g-funk synth whines and Vocodered voices that make you lean further back in the imaginary Impala you’re not riding in. It’s off his latest mixtape, Big Bossin’ Vol 1., which he made entirely with the Texas-based producer Cardo Got Wings, and which is full of similar, smoothly bumping anthems.
