Following the success of Duwap’s breakout track “Santa,” which hit 1 million plays on SoundCloud when he was 15 years old, he presents Forever Kaine, his ambitiously titled debut long-play mixtape. The project finds Duwap streaming one low-key flow into the next, cranking out 10 songs in 20 minutes, barely registering a hook before moving on to the next. The production, courtesy of Pi'erre Bourne and BrentRambo among others, backs Duwap’s auto-tuned lyricism, with a weird, sludgy gumbo of sounds and textures.
