[10][1] She was featured on Bryson Tiller's song "Random Access Memory (RAM)" from his self-titled album, which was also released in March 2024.
[4] Tobias Hess of Paper described La San's music as "an ethereal R&B that has one foot in the early 2000s and the other in a time that doesn't exist yet" and Niall Byrne of Nialler9 called it "nocturnal R&B-pop".
