In any recording of Bach's B minor Mass, we should probably cut the singers some slack. I've sung it--it's HARD!!
And the instrumental parts are no easier. It's a supreme technical and endurance challenge--but oh, so worth it musically. I sometimes think that on my entrance to heaven, I'll hear the trumpets from Dona Nobis Pacem. 
No, for me, et Resurexit. I agree, very demanding, but i recollect that it was intended as several pieces, then put together. There are many wonderful recording.
