Grammy-nominated Nigerian producer DeeYasso emerges into the light with “What Have You Done,” an angsty self-produced track featuring Syemca.

The record is an intentional change to 2026 for DeeYasso. His credits already include Yemi Alade’s Grammy-nominated “Tomorrow,” songs for Dave, Sauti Sol and Oxlade and Chike’s duet “In Love” earlier this year. But each solo performance pushes the narrative further: this is a producer who can also carry an album forward with his own voice. “What Have You Done” makes a more compelling case than anything he has presented before.

Syemca is the ideal voice for this emotional landscape. His recent work with Chike on “Pity My Soul” and “Love Egbugomo” revealed a singer who approaches emotional, R&B-leaning material with genuine warmth. Then in “What Have You Done” he adds the emotional dimension required by the writing, expressing the anguish and uncertainty through his vocal contribution without overshadowing DeeYasso’s performance.

The self-produced arrangement is ambient and mid-tempo through and through. DeeYasso leaves the electronic sounds spacious enough to allow both voices to sit high in the mix. So the emotional intensity of the writing emerges clearly, rather than being lost in a messy production. A heartbreak record needs the vocals up front, and this one strikes the right balance.

The transition from June’s “Let Me Know,” a more playful, attraction-focused track, to “What Have You Done” proves that DeeYasso has charted real emotional breadth in his 2026 output. Each release tells a different story of the same love story.
