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 Cønjuntø Vacíø label and also in the experimental post-punk band Wind Atlas, unveil a new project 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.
