Here is another practice video from Chabanel illustrating the vast superiority of these Psalm settings to the usual fare.
Now, before you say: better to have the Gradual sung, better in Latin, this is not part of the tradition of the Roman Rite, etc. etc., all of this is granted. The way to understand these Psalms are in terms of the existing mainstream practice in 98% of parishes. Let's not let the ideal be the enemy of the vastly better. I like to think of this way. If I were traveling and stopped off at some random parish and heard this Psalm instead of what is usually heard, I would be touched and deeply.
