"Vajra Voices, under the direction of Karen R. Clark, offers a very fine survey of nearly every genre of chant represented in Hildegard’s repertory—antiphons, responsories, hymns, and sequences. Clark herself has a beautiful voice that shows flexibility and nuance through the very broad range that Hildegard covers in her chants. Her performance of the antiphon ‘O Quam Magnum Miraculum Est’ to Shira Kammen’s vielle accompaniment is gorgeous."

“A special vocal group is required to do justice to Hildegard’s music, and we have it here in Vajra Voices, an ensemble of seven women dedicated to mediaeval and modern music. Contralto Karen Clark is the director, and the only instrumental accompaniment is by Shira Kammen on mediaeval harp, and a bowed-stringed instrument called the vielle. A hearty recommendation for this album. I very much enjoyed the full CD of music by Hildegard von Bingen.”

"The seven women of Vajra Voices – richly voiced, contrasted individuals who shine as soloists or conspire without egotism in vivid, full-blooded ensemble – sing out with tremendous intensity. Led by the wide emotional spectrum of Karen R. Clark’s contralto, the shimmering resonance of their elegantly paced performances with entirely credible phrasing and selection of note lengths, coloured at times by instrumental accompaniment, vocal drones, and oganum (sparing and tasteful), is delightful. Lovely, thoughtful, and inspiring instrumentals adorn this, the most convincing Hildegard disc I’ve yet heard from the USA."

"Garrett+Moulton's Divining was a standout piece. Prayerful, spiritual and meditative, but not at all quiet or solemn. A glorious all-female sextet– Vajra Voices directed by Karen R. Clark– sang the early music of Hildegard von Bingen."
"Vajra Voices - an unexpected treat- electric! This seven-voice women’s ensemble, led by Karen R. Clark, delivered the religious music of Hildegard von Bingen in slow, modal statements. Their pure harmonies explored and hallowed a women’s heritage that is nearly one thousand years old, but it felt not only contemporary but almost electric."
---Adam Broner/San Francisco Music Day, 2016
"The music — vocal excerpts by 12th century composer Hildegard von Bingen dispatched splendidly by Vajra Voices — was the most substantial of the evening."
San Francisco Chronicle
"The chant melodies, rendered here with heartfelt elegance by the women’s chorus Vajra Voices under the direction of Karen R. Clark, are striking in both their shapeliness and the spiritual fervor that runs through them."
San Francisco Classical Voice
"Vajra Voices Embodies Hildegard."
