Having watched it more closely.  Is that really a monstrous fan??  Not actually sure.  I don't think the background noise helps.  The video appears to be taken in a room with other demo's going on and so noise is accumulative.  

That said, it isn't the most inspiring performance and as foxy mentions it's riddled with little errors.  It's not hard to do another take and make it more slick.  Would be nice to think we see better content and news in the coming days.
