Orgia Pravednikov (Russian: Оргия Праведников, translated as 'Orgy of The Righteous') is a Russian rock group, which formed in 1999 by uniting the art-rock band «ARTEL» and rock-bard Sergey Kalugin. The peculiar sound of the band arises from the combination of acoustic (flute and acoustic guitar) and electric (drums, electric guitar and bass guitar) sessions.
