When New York rap heavyweight Jadakiss lent his patronage—and the name of his D Block label—to D-Block Europe in 2013, it served notice that the South London collective was one of UK rap’s most promising acts. Strikingly cohesive and consistent, this mixtape is the moment that core duo Young Adz and Dirtbike LB finesse immense potential into top-table quality. Setting skilful wordplay and unshakeable melody to gauzy trap textures, “Kettle Pouring” exemplifies their complete-picture approach, which paints riveting scenes from the club, trap house, bedroom and beyond with equal emphasis on pain and profit, celebration and introspection.
