‘The clarity of intonation and line has the freshness of an illuminated page of manuscript revealed for the first time for two thirds of a millenium’ (Early Music Review)

‘Highly desirable at full price and even more so now. There’s no competition if you want both the Masses together. The Missa Salve regina is the high point of the recording for me—with a gloriously ceremonial organ part and harmonies which are at once of the 20th-century yet harking back to Machaut and before, this music deserves to be much better known and this is the very recording to do it’ (MusicWeb International)

‘This is a superb record, and Hyperion must be congratulated on such an imaginative undertaking. All admirers of the Golden Age of Church Music, and all admirers of the pre-Vatican II rite, should buy a copy. All will treasure it’ (Choir & Organ)

‘Elegant and imaginative … the wind-band pieces are especially gorgeous. [The Mass] receives an opulent interpretation that stands out in a rather crowded field of challengers. Highly recommended’ (Gramophone)

‘A glorious performance … of what must rank among the greatest of Lassus's Mass settings’ (Hi Fi World)

«Une merveille» (Répertoire, France)

‘Absolutely stunning. Lost music re-born’ (BBC Music Magazine)

«Avec un splendide choeur pour le plain-chant, Red Byrd proposent une rencontre vivante et vibrante avec Léonin» (Répertoire, France)

‘A fine contribution to the repertoire on disc of twelfth-century polyphony. A composite sound of great beauty’ (Gramophone)

‘Marvellously atmospheric. A rare and highly rewarding dsc. Brilliant performances of neglected treasures’ (Classic CD)

‘Sung with beguiling beauty. These readings renew our sense of wonder at western music's most fundamental innovation—the sound of two voices simultaneously singing different lines that not only fit with, but also enhance, each other’ (The Sunday Times)

‘An outstanding disc in a trail-blazing series: highly recommended’ (BBC Music Magazine)
