Switzerland's Sum Of R exists since 2008 and was created by Reto Mäder (URAL UMBO, RM74) to construct/deconstruct sound in ways that infest and cloud the interior of the mind. Sum Of R creates slow moving instrumental music with a sensibility for hypnotic and complex song structures. Their intense and pulsating sound is influenced by lumbering doom, drone, post-metal, ambient, noiserock, psychedelic and cinematic post-rock. Sum Of R’s ritualistic take on expanding sound layers is deepened by the rawness of an unconventional metal atmosphere plunged into darkness, light and its reflection. Their live performances as a duo are characterized by a cyclical process involving bass guitars, drums, effects, samples and drones to create a unique and dense whole which is more than the sum of its parts. Sum Of R has played concerts with Amenra (BE), Wolvserpent (USA), Oozing Wound (USA), Asva (USA), Oathbreaker (BE), Wolves In The Throne Room (USA), Corrupted (JP), Pelican (USA), Puma (NOR), Siberian (SWE), Dead Neanderthals (NL), Killl (NOR) a.o.

After the dark and ambient style of the early days of Sum Of R, their music turned into the doom of the new generation, comparable to the development of early Godflesh to Sunn O))).” (Onda Rock, IT) “Sounds like a shipping container being pushed through the mud by hand; every drum thump is its own distinct punctuation rather than an aftermath of the one before, shunting forward the duo's concrete block one inch at a time into a strangely coherent whole.” (Rock-A-Rolla, UK) “The clock goes crazy, the sounds seem to flow forward and backwards at the same time. The sound sources merge into one another and silver vibrations create black whirls.” (Bad Alchemy, GER) “Some of the most attractive aspects of Sum Of R's sound lies in the combination of a sort of ominous apocalyptic imminency, one of the most recurring and reasonable leitmotiv in the range of sources for inspiration, with a certain gore, which gives forth from sometimes unpredictable combustions of doom metal, industrial, instrumental rock and drone.” (Chain D.L.K, USA)
