As the buttery-voiced songwriter Girl Ultra, Mexico City’s Mariana “Nan” de Miguel sings lush, tender, R&B steeped in sensuality and caressed by slippery Latin, hip-hop, and jazz beats. As part of the Finesse Records talent roster, she collaborated with other artists on the FR label and made a name for herself in CDMX’s Boiler Room scene with her covers of tracks by Drake, the Weeknd, and Daniel Caesar. She gained greater attention, however, with her own songs including “Abril,” “Duele,” and “Ella Tu y Yo.” Her 2017 Boys EP established her Latinx-, R&B-drenched grooves internationally while 2018’s Adios EP netted not only magazine articles and cover stories but auspicious entries on streaming and video charts — 2019’s “Dame Love” (featuring Cuco) netted over a-million-and-a-half views during its first two weeks and led the way for the streaming chart success of the lengthy Nuevos Aires. The following year, “Ojos Negro,” a duet with Paula Cendejas, hit the upper rungs of the Spanish charts. In 2021, Girl Ultra was a featured collaborator on Niia’s “If I Should Die.”
