At the beginning of the 12th and 13th centuries, the École de Notre-Dame in Paris was the cradle of European polyphony. From Léonin to Pérotin, vocal music emancipated itself from Gregorian chant and developed into a polyphony of unprecedented complexity and boldness. This art, a true milestone in music history, combines spiritual fervor and architectural rigor in an unparalleled creative drive. The Ensemble Huelgas brings this splendor back to life with historical precision and gripping intensity.
