One of my long-term projects for my parishes here in Piqua is to cultivate as much depth and breadth in our music as I can. We use Gather Comprehensive at St. Boniface; St. Mary uses RitualSong. Gather Comprehensive, by it's own admission, is overwhelmingly "contemporary" -- which means, material published in the last 50 years -- making the title ironic. RitualSong is more like 50/50. (It floored me when I discovered "GIA" -- who publishes these, plus several other hymnals, and is a heavyweight in Catholic hymnals in the U.S. -- stands for . . . "Gregorian Institute of America"!!! I kid you not.) The Gathers are about 10-12 years old, the RitualSong books are 1-2 years old.
Even so, they do have some good resources in them (RS isn't bad, actually), and I am asking our Music Director and our cantors and choirs to go beyond what has been a rather limited repetoire. My advice to my Music Director (who is excellent, and shares my vision): "Plunder the treasures of the Church! It's all ours!"
Here's an example of something nice (I link it for the sound; I hope it works).
