Wow, that was...really impressive. Apart from playing marvelous you two have in some kind of way revolutionized the concept of the concert how it was known until yet. Of course since Youtube there is no need for artist and audience to gather at the same place anymore. But it was the first time for me seeing two artists playing without beeing at the same time and place. What modern composers try to achieve via over-sophisticated and often provocative art-concepts, you two have achieved with a smile.
This feels natural! This is music! I've never enjoyed watching an online video as much like this.
Big Thank You
