The fiddle? I'd guess they went to some trouble to stage that to shock people. And I'd also guess it's a set up for a bad boy image -- borrow a fiddle from someone who is repairing it, or one in need of repair, drop it in the video, and then back to the shop with it.
Or it came from a thrift store, already separated. Someone found it that way.

The back is already lifted when it hits the ground; nothing further breaks; you don't see him throw or drop it; and nothing obvious is damaged further by the fall. No splinters; no stepping on it; nope.

Dropping it would not cause that particular kind of damage IMHO.
