They are raising money doing one of the things they do best: sing! The chant is fantastic, and very valuable for anyone who loves the Gregorian tradition, because the Norbertine books offer a slight variation on the Roman chant. They sing beautifully, based on their last CD of Christmas propers (a CD which I just adore), and this one appears to offer a broader range of music.
The CD is available on Amazon.
