Rels B

Rels B, born Daniel Heredia Vidal, is a Spanish rapper, singer, and producer from Palma de Mallorca. He started out under the name Rels Beats, working primarily as a producer before stepping in front of the mic himself. His early mixtapes and EPs, including «Player Hater» and «Boys Don't Cry», built him a devoted following within Spain's underground hip-hop scene and established the melancholic, introspective yet melodic style that would become his signature.

Rels B distinguished himself by blending trap and hip-hop with R&B melodicism and a distinctly personal, diary-like songwriting approach, often addressing heartbreak, self-doubt and everyday life rather than typical rap bravado. Tracks like «Lejos De Ti» and «Cuéntaselo a Otro» showcase this emotive, melodic side, while songs such as «Mary Jane» and «Diles» lean into a more classic hip-hop groove.

In 2019, Rels B signed with Sony Music Spain and released «Happy Birthday Flakko», an album featuring international collaborations including with the Argentine rapper Duki. The record marked a new stage in his career, expanding his audience across the Spanish-speaking world while retaining the intimate, genre-blending sound that first defined him.
