How can something be excessively perfect? Maybe it's like over abundant or past history.
I suspect the human element is lost or reduced when something becomes so perfect that every drum beat is identical. Sometimes it is the little imperfections or slight variations that give feeling to music... a little emphasis here, a little restraint there. There is a mechanical or machine like sound to the drumming on this album....stunning album, without a doubt, but unsettling to those who fear the Borg ;-)
