In April, the 21-year-old Brooklyn rapper Nfromthewave released his debut single, “Pashun,” a warm, jazzy, and endearingly gawky rough cut all about positivity. Now he has shared a new track, “Everytime,” and its booming club sound is a complete transformation for the still-mysterious artist. With its giant, vibrating bassline, galloping kick drums, and frantic jungle-leaning breakbeat, “Everytime” recreates that feeling of being in the pulsating center of a rave. Nfromthewave jumps into the beat with ease and raps nonchalantly, prancing on top of the music. His lyrical quips might be a little clunky—“Cocaine feel great ‘cause you know it’s South American/But my main bitch from Maryland,” he brags—but the way he leans forward into the production is infectious. Nfromthewave’s cool voice has an immediate gravitational pull, and “Everytime” makes one wonder where he’ll take it next.
