There's TWO guys playing, here, or at least one guy playing most of the time, and the other standing around mostly. Sure, it's a decent demo, but just think... every time the second guy is away from the Tyros, try to think of how many of the sequenced parts he could actually be playing.
Quite a few, IMO.
This is where the 'disconnect' from the audience comes from, the utter disdain for even TRYING to cover most of the bases, and only letting the sequence play what cannot possibly be played, but the willingness to stand around (well away from the keyboard) to make even more obvious that they are listening to a live piano player and little else.
If these two actually tried, I bet they could perform the song just as well, and drop the sequence down to just bass and drums, and little else... And you would have a demo that REALLY rocks!
