"This debut release is as unusual as it is intriguing. It has a ring of purity around it, taking you out of your daily routine whilst inspiring a kind of divine mystery beyond practising earthly religion. Carefully crafted and expertly recorded, including in wide surround, and for those who like it, also available in 4K Video Download, this debut recording has the ethereal power mankind needs in modern testing times."

Adrian Quanjer, HRAudio

"[Kristia] Michael is a vocal artist who navigates between piety and the raw Mediterranean. Subtle are the guttural arabesques with which she adorns the music. The instrumentalists also draw from a rich arsenal, from lute and viola to harp and hurdy-gurdy. An improvisation with percussion and throat singing leaves the Enkhuizen Westerkerk trembling."

Guido van Oorschot, de Volkskrant

"If you enjoy early music and the playing of instruments of that period, this is an album that should be a must buy on your list of future acquisitions. If you enjoy a bit of the mystical with your rebec, all the better! Plus, the performances are gorgeously captured by TRPTK's masterful recording engineer Brendon Heinst."

Rushton Paul, Positive Feedback

"Here the reproduction was almost palpable. What a treat to hear and see these young musicians. With such dedication and intensity, but at the same time with a playful ease. Wow."

Theo Wubbolts, Music Emotion

"The result is pure music arranged and performed with extreme care. Tranquil and contemplative music, with a great link to serenity. Vocal work, such as the opening song O Virtus Sapientiae (H. v. Bingen) has great eloquence. [...] Viriditas is the debut CD of the Sibil-la Ensemble. An album that sounds outstanding not only musically, but also audio-technically."

Mattie Poels, Music Frames

"Thanks to the exquisite qualities of the Sibil-la Ensemble, we can enjoy this music in its purest form, with the gorgeously fine recording crowning this sublime musicianship. A debut album that clearly tastes like more."

Aart van der Wal, OpusKlassiek

"It's one thing for a pianist to conjure the spirit of the time associated with Beethoven or Bach; it's quite another for a group to make the chants and secular songs of the twelfth and thirteenth centuries feel like newly born creations. That's something Sibil•la Ensemble resplendently achieves, however, on its debut album Viriditas."

Ron Schepper, Textura

"[Sibil-la Ensemble's] art is a magnificent paradigm of devoted work on the preservation and development of European music heritage, their focus on Medieval, Renaissance and Baroque music underlined a decisive field of the cultural interdisciplinary character of European heritage."
