The glorious and immortal gregorian chanting engenders great spiritual fruits. The religious people and the cantors defending and widespreading the gregorian songs do a great work for the benefit of the souls and therefore for the major glory of God. We must not allow that such a precious treasure transmitted by our ancestors will be lost.
You may find amatorial records of several gregorian songs sang by the Benedectines of Sao Paulo, Brazil. You can download the songs for free and you can also reproduce and forward them widely. Please, note that the server might be slow. About 20 songs have been uploaded in a zip file, which should be quicker. The chanting's quality is not professional, but the record will be useful to help become more familiar with the Gregorian tradition. I usually listen to these songs while I am doing spiritual readings or I am praying.
