… the performance is very informed about what it is like to sing in such a space and that will these performances quite revelatory. … The accompanying booklet provides an excellent overview of the music here and the process used to recreate the sound of this ancient building within the concert hall at Stanford.  There is also an accompanying BluRay which features a 23-minute documentary about the unique sonic qualities of the building.  Certainly an important release for those who appreciate early music and a must have for those teaching Medieval period music. … Highly Recommended!
