With a rich display of medieval polyphonic works and Gregorian chant illustrating the theme of the 'Tree of Jesse', the Ensemble Gilles Binchois turn their attention to biblical texts with a clarity that calls to mind the intricacy of illuminated manuscripts, the vitality of stained-glass windows and the bold colours of both. And with a freshness belying nearly 30 years of performing activity and research which have nurtured a deep understanding and awareness of medieval liturgical music on the part of Vellard and a small group of his closest collaborators. The redoubled enthusiasm and energy of the Ensemble Gilles Binchois, so audible on L'arbre de Jessé, are set to form a highlight of Glossa's releases over coming years with promised forays into the early Baroque and the great polyphony of the 16th-century.
