Following 2014's full-length Unknown Memory, Swedish rapper Yung Lean issued his third LP, Stranger, a hazy narcotic that's ideal for altered states or simply lulling oneself to sleep. While the production provided by Yung Gud improves upon its predecessor, Stranger is hypnotic in a way that anesthetizes rather than enthralls. Icy and detached, it has some highlights that pull listeners out of the fog. "Red Bottom Sky" is a rare tender pop moment that betrays Lean's attempts to be hardcore, instead resulting in an almost precious effect. "Hunting My Own Skin" is similarly "upbeat," riding a catchy melody that's the most buoyant on the album. The rest of Stranger maintains a steady, low-energy flow, as Lean raps about drugs, sex, and his mental state. Album closer "Yellowman" -- inspired by The King in Yellow -- is an atmospheric journey through Lean's psyche, linking the short stories to his mental health state. Stranger has its cloud-rap niche and should please listeners eager to enter this world, but casual rap fans should arm themselves with enough patience and caffeine before taking the plunge.
