This is one of the amazing things you can see in New York City:
These two creatures are one of four in a group called the Xylopholks. According to their website, all are well-schooled in music and play different venues around the city to entertain us human folk.
The clip I provided doesn’t really do them justice (I was only using my camera video recorder), so check out their website (www.xylopholks.com) and see how wonderful they really are!
