SDH (Semiotics Department of Heteronyms) is the new project of two key figures of the synth-wave/industrial scene of Barcelona. Andrea P. Latorre and Sergi Algiz, founders of the Conjunto Vacío label and also in the post-punk band Wind Atlas, unveil a new act more oriented towards pop music. SDH is change, alteration, distortion, metamorphosis. Their synth-pop songs, sprinkled with EBM and techno, are mysterious, obtuse and suggestive. With only two songs published, they have already supported artists such as Marie Davidson and Merchandise and performed at the Swedish festival Kalabalik På Tyrolen, one of the reference festivals of the darkwave scene.
