Psalm 15, Marco den Toom

Here is the 15th psalm from the psalm book of Marco den Toom. I hope to keep on like this, bu maybe the upload frequency goes down a bit since I volunteered to give keyboard lessons to an Ethiopien refugee who wants to learn keyboard to serve in the church he started with a little group.

The youtube version is without tremulant, while the other version is with tremulant. Which do you prefer?
