Gyakusatsu is the solo project of Òscar from the catalan band Persona. In this project he explores noise, industrial and harsh sounds. It is based upon religious repressions and extorsions along history, the brutality of our society and the interest in serial killers, sex perversions, etc. The lyrics are Òscar's texts and also Ancient Testament excerpts, serial killer's speeches, etc. The sound of Gyakusatsu mixes samplers, handmade instruments and gadgets' noise, different distortion pedals, computer and synthetizer, and of course, distorted voice. The artworks and logo band are made by the other half of Persona, Desirée.
