Orgia Pravednikov (Оргия Праведников, 'Orgy of The Righteous') is a Russian rock band, which was founded in early 1999, when guitarist Sergei Kalugin and the Moscow art-rock band «ARТель» joined together. The original sound of the group is determined by the combination of acoustic (flute and acoustic guitar) and electric (percussion, electric guitar and bass guitar) sections.
