Pendulum Nisum are Reto Mäder (Ural Umbo, Sum Of R, RM74) and Mike Reber (Herpes Ö DeLuxe). The 8 pieces on their debut album are built on majestic organic drones and hypnotic, sinister melodies - a complex structured sound built from horns, organ, piano, analogue synthesizers, shades of guitar sounds, voices, found objects, electro-acoustic processes, and, most of all, an unusual strong presence of field recordings. The powerful but warm and gloomy sound, based on acoustic instruments and electronic sound treatment clashes in a challenging way with the carefully selected natural sounds (thunderstorms, rain, city noises) chosen from the huge sound databank that Reber has collected within the last decade. Reto Mder works solo as RM74 and in the groups Ural Umbo (with Steven Hess from Chicago) and Sum Of R. In 2006 he collaborated with Ralf Wehowsky RLW for the Crouton release Pirouetten. He produced albums for Rhys Chatham (The Bern Project, 2009). Since 2006 Reto Mder has run the label Hinterzimmer Records together with Roger Ziegler. Mike Reber is member of the band Herpes Ö DeLuxe. Since 1995 they have worked in a musical field between atmospheric noise, electronica bruitiste, sombre soundscapes and harsh drones. Hinterzimmer Records released their two last proper albums Kielholen and Ember. Reber also used to work as performance artist during the 80ies and 90ies and has acted in several theatre pieces.
