Slade Da Monsta emerged from the same city as so many other sterling hip-hop producers and artists: Atlanta. The beatmaker began scoring placements in the mid-2010s, less with artists from his hometown than with stars raised on the internet. He’s concocted lo-fi, distorted wonders for Lil Uzi Vert, electrifying trap bangers for Cardi B, and warm, melodious beats for NYC crooner A Boogie wit da Hoodie.
