Up Next: A Pop Ingénue Who Sings With Solange and Blood Orange

Name: Eva Tolkin

Age: 30

Hometown: Toronto

Now Lives: A one-bedroom garden apartment in the Williamsburg neighborhood of Brooklyn.

Claim to Fame: A former backup singer for Solange Knowles and Lykke Li, Ms. Tolkin is a nascent pop star and fashion plate who evokes early Madonna and the effervescent melodies of Robyn.

Like those pop heavyweights, Ms. Tolkin goes by only her first name, though she probably takes her stage name less seriously. “It’s hard to look for just ‘Eva’ online, which has made my life a bit difficult,” she said, laughing.

Big Break: In 2013, Ms. Tolkin met Imogene Strauss, a former curator of MoMA P. S. 1’s Warm Up series, who managed Solange. The two hit it off, and, years later, Ms. Strauss was using Ms. Tolkin’s apartment to audition backup vocalists.

“At the time I was obsessed with Solange, so I thought, ‘You know what? I am going to audition, too,’” Ms. Tolkin said. After four rounds of casting, she got the gig. One week later, she performed at the Pitchfork Music Festival. “I didn’t even know how to use my ear monitor correctly,” she said.

Latest Project: After self-releasing her debut EP, “Evergreen,” last year, Ms. Tolkin signed to the indie music imprint B4. Her single “Touch Me,” a shimmery dance-floor ode to masturbation, was released in August. “I’m not overly idealistic with my songwriting,” she said. “I’m more interested in the grittiness and raunchiness of relationships.”

Next Thing: Ms. Tolkin’s vocals appear on three tracks on “Negro Swan,” the new album by Dev Hynes, a.k.a. Blood Orange, another artist Ms. Strauss managed. Although Ms. Tolkin is joining Mr. Hynes on tour this fall, she is scheduling some time for herself. She will perform a solo show at Baby’s All Right in Brooklyn on Nov. 26.

Self-Styled: Whether it’s appearing in The Fader or her music videos, Ms. Tolkin is meticulous about her wardrobe. She is currently obsessed with vintage Prada, Jean Paul Gaultier and Moschino from the 1990s and early 2000s. “I feel responsible to reuse things and be environmentally friendly,” she said. Occasionally, she breaks her own eco-rules. On a recent day trip to Fire Island, she paired a vintage Mark Wong Nark dress with a new Jacquemus straw hat.
