“Quia Nesciunt Quid Faciunt” is the newest – 11th – full-length studio Roz Vitalis album – and 3rd album at Lizard Records – released five and a half years after the band's most famous release – 10th studio disc “The Hidden Man of the Heart” (2018). “Quia Nesciunt Quid Faciunt” (“they know not what they do” translated from Latin) consists of 10 tracks and lasts 54 minutes. The title of the album was induced by tragic events of the latest years concerned with military operations and violation of human rights in some regions of the world.

The Russian band Roz Vitalis (from Saint Petersburg) exists since 2001 as a studio project, since 2005 as an electroacoustic chamber ensemble and since 2008 as a full-blown rock-band. Style of Roz Vitalis music can be described as the "Unclassifiable Branch of Prog Rock", Avant Prog, Sympho Prog, Instumental. The "metaphysical" goals of Roz Vitalis are "per musica ad lucem" and "to overcome chaos by means of making music". The main influences are Gentle Giant, Univers Zero, King Crimson, Le Orme, Yes.

“The Hidden Man of the Heart” is most ambitious, grandiose and high-flying opus of the band at the present moment. It consists of 14 tracks and lasts 63 minutes. Various keyboards, guitars, bass, drums, flute and trumpet are supplemented by exotic kinds of percussion, mandolin, bass clarinet and even string quartet! It is that this album extremely emphasizes strange combination of memorable/hooking melodies and sophisticated compositional structures with complex system of leitmotivs. Such combination of “familiarity and weirdness” is one of the trademarks of ROZ VITALIS.
