Lights keep on shining in the dark according to the incisive stylistical concoction by original Swiss musician Reto Mader aka RM74, who releases the second full lenght album of his side-project Sum OF R together with Julia Valentina Wolf after the tidbit "Ride out the Waves" on Storm As He Walks. "Lights on Water" sounds maybe less visceral and more geometrical than the above-mentioned EP as if some structures had been conceived in order to ease "compatibility" with possible live stages and some sonic contrivances are often easily reproducible, but their sound remains tremendously hard-hitting and cliffhanging. In order to give you an idea of their strking sonic strategies to melt doom metal, noisy hooks and ritual guise, the sepulchral chords, which got gradually saturated before exploding, on the initial "Rays and Line Segments" could be thought as a mixture of tricks by Cranes, Death In Vegas, Starfish Enterprises and GYBE; the ominous "Not Today and Maybe Not Tomorrow But Soon And For the Rest of Your Life" seems to follow the same path before the guitar gets dried and when you would expect a sort of depressive ballad, Mader's drumming coerces guitar into discharging cathartic and electric crimping and foretelling a curse. After the pre-apocalyptic medley "Birds Were Fallign From The Sky" and the caustic compressions of "In Mirror Arms", where doom metal vein by Sum Of R can be easily palpated, "Nobody Wants To Trade Uncommons For Uncommons" is maybe the track which includes more bromidic tricks, but they soon boost liking by the creepy scuffs of "Vela" and the final "March Out of Step When Crossing a Bridge", where their proper winning feature that is the balance between frail and blasting by means of a concatenating element - on this occasion a march-like tempo - is by far more appreciable.
