Ensemble MARE NOSTRUM, a roman ensemble directed by Andrea De Carlo, is one of the most original and surprising baroque ensembles, already a reference to the Roman Baroque music and especially the works of the great composer Alessandro Stradella. Founded in 2005, the Ensemble Mare Nostrum begins as a "Consort of Viols". But the ensemble opens immediately to a wider repertoire, to explore the relationship between phonetic, language, affetti and nature of sounds. The personal research of Andrea De Carlo in this field opens new prospects in technique and aesthetic of 17th c. vocal music. The 2013 saw the birth of THE STRADELLA PROJECT, a CDs collection for the label ARCANA (OUTHERE) dedicated to the works of this great composer, recorded in the International Festival Alessandro Stradella Nepi (Italy).
