Positive Centre is the dark ambient project of Berlin based Artist, Mike Jefford. Using a collection of analog synthesizers, effects processors and tape machines: Positive Centre is an exploration into the possibilities of depth, width and texture reproduction through loud speakers. Being influenced by the GRM (Groupe de Recherches Musicales) School Masters: Pierre Henry and Iannis Xenakis as well as more contemporary manipulators of sound (from King Tubby and Scientist to Marsen Jules and Aphex Twin). Positive Centre takes the exploration of sound reproduction and audio collage into rhythmic and hypnotic spirals of reverberated walls of sound, with an emphasis on subtle changes in repetition and low frequency sound. In September 2013, the first Positive Centre record was released on Sigha's Our Circula Sound imprint. Featuring six tracks of slowed and swung techno under the title 'An Assembly', which were all mastered by Matt Colton at Alchemy Studios. Positive Centre is set to return to Our Circula Sound with a four track EP of darker, more anxious sounds entitled 'Hiding Knives' in January 2014.
