My mom sent me a video clip of a guy juggling balls onto a piano keyboard, playing all kinds of complicated melodies with chords and everything.  I found a copy of the clip on the web over here if you want to check it out.  As a musician and a juggler (former juggler?  non-practicing juggler I guess) this was driving me crazy, I had to know if it was for real or not.  I asked Harper but he wasn’t sure.  My verdict is NO.  He’s a great juggler but there’s no way on earth that the notes you hear out the speakers are corresponding to the same notes he’s hitting on the keyboard.  Gotta be using a sequencer, and the balls must be just triggering the notes.  Still… pretty amazing showmanship there, you gotta give him that much.
