This is the most AMAZING collection of Christmas carols!
It includes many hard-to-find gems, such as "Cherry Tree Carol", "Jesus Christ the Apple Tree", "Three Kings", Darke's "In the Bleak Midwinter" (as well as the more famous & congregation-friendly setting by Holst), "Bethlehem Down", and several of the Oxford Descants. If you take a look at the table of contents, that alone should sell you. The editor's work in compiling this book was incredible. The voicing of the 4 (or more) part harmony in each of the carols is consistently excellent, performance-grade material.
This book is truly the best of its kind available, and for $35.00, it's quite a steal.
