This recording comes into the framework of the research undertaken some fifteen years ago by Yann Fañch Kemener and Aldo Ripoche, on traditional music from Basse -Bretagne and erudite music. Based on one of the high points of Christianity -Easter- this repertoire is linked to the sung ritual of the Passion as it was carried out in Central Brittany until WW II. It also includes songs pertaining to the Marian cult, as well as the hymn 'O Filii' written by P.F. Olivier Aubert for two cellos. Bonus CD: a recording of a concert by Yann Fañch Kemener and Aldo Ripoche - Songs and tales - in Sainte Trephine.
