Flores - "Undercover (Prod. Maths Time Joy)"
Flores and Maths Time Joy have worked together before, and here's hoping they keep at it. "Undercover" follows on the heels of "Oceans" and "After Hours," but this might be their most ambitious collaboration yet. The L.A.-born, Norway-based singer's vocals are stacked in overlapping harmonies over deep, full production that can stop on a dime or build to dizzying towers of synth. These two are sounding like the future of R&B, and they're making it look easy.—Graham Corrigan
