2011 release ** "'Opus Tartari' is the latest album of Italian dark ambient project which - in its leader's own words - after years of esoteric and alchemist studies decided to transfer his own experiences into music. Ouroboros should be then treated as a medium used in search for its own philosophical stone. Compositions included on the album lead the listener into the world of antique and medieval times due to their tunes and the singing in Latin. Mystical, slightly sacral character of the tracks has become its leitmotif recognisible for the band. Marco Grosso known for his collaboration with many session musicians (with Claudio Dondo of Runes Order) asked a lot of vocalists (Nuna Luna - soprano voice, Sorath Isis, Aleph Zero, Malice) to participate in the recordings as well. This resulted in the creation of 'Opus Tartari' - an intriguing, emotional, full of unsettling beauty and esoterica journey. The album can be likened to early releases of Diamanda Galas, The Moon and the Nightspirit and The Moon Lay Hidden Beneath a Cloud."
