Lacks the power base for the left hand.7/9/2013 4:18pm
The stuff they prepared for piano was for an easy-type. It lacks the power base for the left hand, in which others in the youtubes played by different pianists. Accuracy is okay, good enough if you are in a hurry to master it, but if you are looking for a strong base-sound try others in the internet youtube. The only downfall is that they are pretty much for advance-pianist, but its worth the essence in the end.
