While you can watch it below, I'd recommend going to YouTube and watching it in high def. Credit to lives_this_life for finding it.
I know a lot of people on my friends list knit, so this might amuse them: Kint your pie crusts!
I'm not sure this is good for a piano, but what a cool video it makes! The camerawork was clever (loved the dog cam!) and the house is beautiful. (In my headcanon, the four are totally in love and live in that house. Makes the video even happier to me!)
It really amazes me all the sounds they can get out of one piano, some string(?), and a piece of paper. (Make sure you watch all the way to the very end for the post-"credit" stuff.)
