G Herbo’s tough, tenacious street-rap style is laid out in brutal detail on his potent fourth mixtape, Strictly 4 My Fans. On “Run It Up,” he rides some tenement-sized riffs, booming bass, and heavy percussion, offering a rattling, pavement-crumbling encapsulation of Chicago drill music. The rapper switches things up on the Auto-Tuned “Control,” its ugly-beautiful synthetic vocals and horror-movie piano keys helping Herb recall a doomed romance with bitter vehemence.
