The amazing creation lives, and that is an accomplishment, but like the Shelley creation, something is not quite right. To start with, the drum sounds themselves are canned. They are played by a human but they sound like a drum machine. That's because the sound comes from a drum machine. The sounds have a definite continuity to them, but they lack dynamic finesse.
Real drums have a nearly infinite variety of timbres and volumes.
This drum machine appears to come in soft, medium and loud. So while the CD totes the singing as canned, it appears to this listener that it is the drumming which is canned. This is through no fault of Clarence, by the way. It's just the limitation of the technology. Perhaps the answer is that the drum machine provides an extremely wide variety of different sounds.
