Silent Future is a collaborative album of lush, hypnotic and megalithic ambience, a righteously thick, molten-tempo journey into the unknown. For fans of Russian Circles, Pelican, YOB, Pallbearer, OM, Elder, Dead Meadow, The Otolith … On Silent Future, Chicago atmospheric psych-doom outfit REZN teams up with Mexico City cosmic conceptualists Vinnum Sabbathi for a true union of heavy exploration. Allowing themselves a fluid, open canvas to experiment, members of both bands contribute equally to create an album of lush, hypnotic and frequently megalithic ambience, yielding an utterly cohesive trip into the riff-drenched astral reaches. The fluidity with which REZN and Vinnum Sabbathi collaborate is unlikely, yet inarguable. Strong nuclear forces conjoin sections as alternatingly ethereal as celestial light and dense as a black hole collapse. Ultimately, the endeavor is never limited to being one thing for long, any more than it is limited to being the work of a single band. More than a listening experience, Silent Future's vitality extends beyond the aural. This is the work of two groups pushing themselves further than they've gone before, each answering the other's question of how far they can ultimately go. As heavy as Silent Future gets, as distant as it may range, one cannot regard this righteously thick, molten-tempo journey into the unknown as anything but breathtaking.
