The National Association of Pastoral Musicians has recorded some Missal chants from the new translation. Find them here. (“Recordings of chants from The Roman Missal © 2010, National Association of Pastoral Musicians (NPM). All rights reserved.”)
The Church Music Association of America’s versions are here. (“Recordings of chant from The Roman Missal that you can borrow, sell, propagate, or anything else. All rights freely shared with the world.”)
They do make for an interesting comparison.
