The British rapper’s laser focus has been trained on fame since she was a child. Now, she’s ready to take it to the next level.LONDON — Long before she was famous here as the rapper Little Simz, Simbiatu Abisola Abiola Ajikawo, known as Simbi, made her debut performance at a local youth club showcase. Ten years old and wearing a red Ecko tracksuit, her hair parted in two bunches, she lunged to the edge of the stage, almost collapsing into her classmates in the front row, and rapped: “In 10 years, I want to be a performer that can entertain, and still remain, to do good things in life.”More than a decade has passed, and Little Simz, now 27, is living up to her ambitions. Her fourth album, “Sometimes I Might Be Introvert,” is due on Sept. 3. As an actor, she has starred in British TV shows, including Ronan Bennet’s breakout hit, “Top Boy.” She is an active member of her community in Islington, North London, doing good through charitable acts she “doesn’t feel the need to be loud about,” she said.A master storyteller who raps with wisdom and heart, Little Simz has a narrative style that’s been likened to Kendrick Lamar and J. Cole, both fans of her work. Where she was once just “your favorite rapper’s favorite rapper,” she is becoming a household name here in her own right.In 2019, the grime star Stormzy shouted out Little Simz as an up-and-comer to watch during his headlining set at the Glastonbury Festival. That same year, her third studio LP, “Grey Area,” a grooving and eclectic rumination on her early 20s, was named best British album at the NME Awards.But now, poised to release her latest album, she feels on the cusp of something really big, she said in a recent interview, as she lounged gracefully on a restaurant sofa in King’s Cross, London, as though it were her own. “Everyone has their moment,” she said, “and I think ‘Sometimes I Might Be Introvert’ will be mine.”“I’m still young, innit?” she added. “But I know that’s where I’m heading.”Kadeem Clarke, a frequent collaborator who directs Little Simz’s live performances, said her determination was unshakable. “She has a vision, and we don’t even know where it comes from, or how it’s going to get done, but she does it,” he said. “She will not take her eye off it.”That laser focus has been a hallmark since Little Simz’s North London childhood. Her house was crowded, noisy and alive, she recalled: Her mother played Afrobeats and reggae, her sisters garage and grime, her brothers rap and hip-hop.In her bedroom, Little Simz listened to Busta Rhymes, Nas and Biggie Smalls, and dreamed of being like them, she said: a rap legend who spoke to their listener, not at them. She wrote their lyrics out in notebooks, trying to work out how the artists turned stubborn words into something slick and percussive. The natural and chatty approach of Biggie Smalls, in particular, drew her in: “If you took away his flow and instrumental, he could just be talking to you.”She said that she had “struggled to articulate myself in conversation,” but that her own rapping, which she thought of as a dialogue with herself, helped make sense of her thoughts. “And then, I even question it — like, why do I think that?”In rapping, she said, she found the thing that set her apart from her peers. “Everyone knew me as that girl who rapped,” she explained. “I’m the youngest of four, and my older siblings knew everyone, so I was always, ‘T’s little sister,’ or ‘Fem’s little sister.’ Then other people would find out that I did music, and it’d be another layer, like, ‘Aw, you know T’s sister raps?’”Claire Hough and Little Simz shooting the video for her new song “Introvert.”Tamiym CaderAt 14, Little Simz began making sacrifices for the hobby she was determined to turn into a career: She stayed in when her friends went out together on weekends, saving her pocket money for studio equipment. Her bedroom became a shrine to her musical idols, with posters of Lauryn Hill, Nas and Jay-Z, and a photo of herself placed above them. On a piece of cardboard, she wrote an affirmation in all caps: “Dream big! Family is everything! God is love! Be great!”That same year, she landed an acting role on a BBC children’s adventure show, “Spirit Warriors.” Later, at 17, Little Simz was cast in “Youngers,” a children’s drama depicting a group of London teenagers hoping to make it big in music. Life began to imitate art when she formed a group called Space Age with other young musicians and artists she met at EC1 Music Project, another London community program. The crew became a kind of extended family, Little Simz said, playing instruments, adding vocals and producing visual art for the mixtapes she began recording.Tilla Arcé, a close friend who also rapped in Space Age, said, “Simz always surrounded herself with real people,” but noted she was more inclined to open up in her music than in social settings. “When she’s performing, it’s her space to let go and be immersed in pure emotion and expression,” he said. “Simbi the person is a lot more to herself, but because I’ve known her as a virtuoso, I understand the moments she taps into Little Simz.”Space Age’s members joined in on Little Simz’s debut album “A Curious Tale of Trials + Persons,” which she released when she was 20: Arcé recorded additional vocals, and his brother, Josh, helmed the production on several tracks. The album is a reflection on fame and its effects on the human spirit, with Little Simz adopting new personas on different songs, each one a character at a different stage of their journey to celebrity. How about that as a statement of intent?With the release of “Sometimes I Might Be Introvert,” Little Simz said she was ready to move to the next level: “There’s just something in the air.” Featuring interludes voiced by Emma Corrin, who played Princess Diana in “The Crown,” the 19-track album is an odyssey through Little Simz’s inner conflicts and joys. Bringing together influences including lackadaisical neo-soul and ’80s electro funk, it has the scope and spectacle of a West End production.Little Simz recorded the album in Los Angeles, working with Dean Josiah Cover, 33, who produces under the name InFlo. He is, like the members of Space Age, both a childhood friend and a persistent influence on her music. The two have been collaborating since Little Simz was a dream-driven teen, in 2008.“When I listen to the stuff we made back then, it sounds almost like ‘Sometimes I Might Be Introvert,’” she said. Both artists’ tastes and sound palettes are far-ranging, taking in hip-hop, jazz, R&B, punk and soul. “We literally have a brother-sister relationship,” Little Simz said. “I annoy him, he annoys me. But we make great music together,” she said, describing their creative process as a safe space: “Whatever you feel, it’s between these four walls, and if it goes on the record then it does, if it doesn’t, it doesn’t. Shout, scream, cry, whatever it is.”With all that space for self-examination, Little Simz’s ambitions didn’t go without self- scrutiny: “Why the desperate need to be remembered? Everybody knowing what you’ve done, how far you’ve come?” Little Simz raps on “Standing Ovation,” one of the new album’s tracks.In the interview, she said she was willing to sacrifice a lot for the big time she saw coming, not least her privacy. “If I didn’t do music, no one would know who I am,” she said. The comfort of invisibility appealed to her introverted side, but she has struck a bargain: “I’m not going to be nameless. I want my music to be known, I want my music to be heard, I want to tell my story.”But fame isn’t the be-all and end-all, Little Simz added. “I’m trying to be my greatest self in all aspects of my life, and not just music,” she said. Echoing the song she performed as a 10-year-old, she reiterated her purpose: “Not only am I trying to be a great artist and performer, I’m trying to be a great sister, friend, daughter, auntie.” More
