When Ari Lennox released her debut, Shea Butter Baby, in 2019, she had just moved into her first solo apartment. In recent years, Lennox says, she’s also gotten sober and started dating with greater intention. 0.0On Vacancy, Lennox sings with the self-knowledge of a grown woman: Instead of reassuring herself that she calls the shots, she now tells partners exactly how long they have to text her back before she moves on (“24 Seconds”). She doesn’t need to return to old techniques, but as it stands, Vacancy sometimes feels composed to the point of redundancy. Like in Shea Butter Baby’s “New Apartment,” Lennox uses the image of home to understand the life she wants.
