This is a great recording. The music itself is ethereal and transporting, and the voices are magical and pure. I've had it on the CD player in the car for about a month now.
The chants themselves are not as ornate as some Byzantine music, but the drone effects and the translucent discants create a complexity that has me listening again and again.
The music itself is good, and the execution of it is excellent,. I heartily recommend this CD.
