This is a compilation of previously released vocal and instrumental music by several excellent groups.
Three tracts are by the Waverly Consort. Their Ave Maria, by Joaquin Desprez is a great find, of all of the many versions this one is my favorite - the voices and instruments blend perfectly! I wore out my vinyl album years ago and am so grateful to have found this tract on CD. The album is more than worth the cost, especially if you collect the Waverly Consort.
The other vocal groups are also excellent. There is something for everyone in this compilation, and this collection is a good place to start. My only reservation is that it is a compilation and I would rather have the whole albums, but as with the Waverly Consort, many of the albums are not on CD.
