"The project Mare Balticum aims to present the medieval musical heritage of the Baltic Sea region in the 12th-15th centuries, with this first volume focussing on Denmark ... The series provides an insight into the local literature and musical repertories of medieval Denmark, Sweden, Finland, Germany, and Poland; both Latin and the vernacular are represented, as well as the diversity of historical musical instruments used in those regions at the time ... All of which are essential to our understanding of the common identity and history of Balticum, as is reflected to us through its centuries of music. Ensemble Peregrina is one of the leading ensembles dedicated to the performance of early medieval vocal music".
