Yung Lean is a cherubic-looking teenage rapper from Stockholm, Sweden, who’s uncannily obsessed with AriZona Iced Tea. He’s the figurehead of the Sadboys crew, who, to judge by their music videos, spend much of their time consuming junk food and concocting sexual fantasies in the idyllic Swedish countryside. In “Ginseng Strip 2002,” Yung Lean likens himself to a peeled banana and enumerates odd places to stick his member, all in a plodding, understated, and stoic cadence that betrays a mild accent. Clearly, he’s studied American rap’s most askew emissions, such as Lil B, from the vantage point of a country with little cultural precedent for hip-hop idiosyncrasy. Fittingly, Yung Lean has collaborated with Friendzone, a sought-after local production duo whose suburban, gated-community backstory also bucks flimsy notions of hip-hop authenticity. Yung Lean’s appeal is largely novel, but peculiarity can be enthralling entertainment, and even art.
