Yuri Wichniakov (Russian: Юрий Вишняков) is a Russian oktavist singer known for his powerful lower register, and resonant low notes. He is the featured bass on the CD Basso Profondo From Old Russia.[1] Wichniakov performs notes as low as E1. Several of the choir directors he has performed with have compared the timbre of his voice to that of an organ.
Together with Vladimir Miller and the late Vladimir Pasyoukov, Wichniakov is widely regarded as one of the most prominent basso profondo singers in the world. He has chanted with Vladimir Miller in several concerts dating back to 2005, and has also performed alongside Pasyukov.
