After five minutes of classical music in a strictly straight-faced, show-off virtuoso style, from a string quartet in coat-tails and white bow-ties, the first signs of slapstick start to appear.

Flawless choreography means the show runs like a Swiss watch, and they manage flamenco dancing while still playing cello. Already liking classical music obviously helps but if not, the foursome do a good job of giving clowning a modern twist, and making innocent, child-friendly entertainment along the same lines as actors like Roberto Benigni or Charlie Chaplin.
