Oslo's Trio Mediaeval presents a reconstruction of a 13th century votive Mass to the Virgin Mary, based on surviving manuscripts from a Benedictine Abbey in the English Midlands. Inserted amid the medieval music are a Credo and Benedicamus Domino specially composed for this programme by Gavin Bryars: the old and the new intermingle in the work of this vocal ensemble. Anna Maria Friman: "The members of Trio Mediaeval feel that performing medieval music today gives us the freedom to let our imagination and ideas flow, as though we are creating contemporary music."
