Right off the bat, in a font reminiscent of posters for feature films, she lets you know: the music, writing, story, and casting for the “Slide” video was all done by Shellz. Those familiar with the Boston-born Haitian-American singer, rapper, and songwriter won’t be surprised. Shellz has never had any difficulty taking charge. Self-assertion is a major theme of the swaggering No Category, her acclaimed 2018 mixtape, and her statements of purpose only intensified on –ily, the electrifying follow-up. However, as brassy as she can be, there’s a sensitive side of Shellz, too. The intense push and pull between independence and emotional attachment is the subject of the “Slide” clip – and Shellz, frank and forthright as always, makes that delicate balancing act manifest for her viewers and listeners. The song has already been shaking up the airwaves: the independently released “Slide” has been spun on urban stations across the country, and each week, it seems like more programmers are catching on to this dazzling new voice. It’s being played commercially and is currently the #1 most-added track at college radio. On “Slide,” Shellz announces her presence with authority, and demonstrates her flexibility, too – she sings seductively through artful vocal processing, and then raps, explosively, over a skittering trap beat. Shellz, who was a deejay before she was a recording artist, has always been skilled at synthesizing style, and here, she puts that trained ear to work, effortlessly fusing pop, late-night R&B, hip-hop, and a pinch of island music, too. That eclectic approach is present throughout Thirst Trappin’, the latest Shellz project. It’s the statement of a young artist coming into her own – one deeply rooted in her independent scene, but with an eye on national recognition. JaeStar’s crisply-made video for “Slide” presents Shellz as a budding star: a camera-ready, charismatic screen presence whose every glance and gesture tells a powerful story. The “Slide” clip dramatizes the song’s narrative – in it, Shellz is torn between her desire to assert her independence and her attachment to a boyfriend who appears to be putting work above their relationship. Text messages go unanswered, hours tick by; finally, Shellz takes matters in her own hands and heads to the recording studio where her boyfriend works. Confrontation, frustration, resolution: everything that makes up hip-hop drama is here in a three-minute package. Nevertheless, JaeStar makes sure to include plenty of footage of Shellz in performance, rocking the microphone in an art studio space with graffiti-decked walls.
