Orgia Pravednikov is a Russian rock group formed in 1999. The peculiar sound of the band arises from the combination of acoustic and electric sessions.

The band "Marco Polo" was founded in the spring of 2014 by three founders - Lyudmila Savostianova (music, lyrics, vocals, arrangement), Vadim Savostianov (Director, producer, PR-Manager) and Pavel Salomatin (bassist).

Generally, the band's music can be classified as "folk-rock", but the work of "Marco Polo" is hard to characterize in any style. Ludmila Savostyanova uses different approaches in every song she writes and tries to consider every composition as a soundtrack to some movie or the story. Thus, various style elements penetrate in the music, such as, for example, neo-classical, folk, hard rock, power metal, etc.
