On his debut, the foul-mouthed, fleet-tongued alter ego of social media star George “Filthy Frank” Miller flexes his battle-rap skills and ability to flip any situation into an occasion for expletive-studded stunting. He revels in his carnal side, satirises various online subcultures and relives high-school traumas over dime-store trap beats, while parodic homages to cavernous electro (on “Club Banger 3000”) and angsty pop-punk (on “High School Blink193”) round out his cheerily nihilistic, acridly humorous worldview.
