Noah and Sydney Lee are a brother and sister from Oakland, New Jersey. They also happen to be talented cellists.
They've appeared on NPR's From the Top (which you can hear Sundays at noon on Classical MPR), and recently, filmmaker Dillon Buss and animator Jack Quinn collaborated on a video using a technique called rotoscoping, in which live action video is traced and animated.
In the video, the siblings perform Johann Halvorsen's Passacaglia in G Minor on a Theme by Handel. Check it out below.
