The premiere CD of Il Illo Tempore edition whose authors have focused on the revival of the music monuments from the area of present Slovakia up to the year 1600. Even though it would be difficult to find such monuments in a big amount in the Slovak museums and archives they are still worth of our attention. These are mostly manuscript text books of homophonic choral liturgical chants as well as polyphonic chants of the same intention. As the title suggests, Gregoriana has chosen for its first CD chants intended for the advent period of the liturgical year. In frame of the first part the authors attempted to make a reconstruction of the first advent vespers (celebrated on Saturday before the first advent Sunday) after the Bratislava antiphon IV., according to instructions from the Jager Ordinary (Ordinarius Agriense). The second part of the album contains the mass chants for the first advent Sunday, mostly chants from the Bratislava neume missal. www.gregoriana.sk
