Box animation

A man enters a room with drum sticks in his hand as he approaches a drum sets and starts to play. As he starts to play, dull coloured boxes positioned infront of him sudenly turn bright colours and begin to float in tune with the mans music. When the man is finished playing, smaller boxes erupt from the tops of the origional boxes and the mans friends applaud his preformance.
At the beginning of the video the camera is mainly focused on the man following his every move. When he approaches the drum set he is still in the foreground but the focus of the camera is on the boxes. The man is  mearely there to provide an audio effect for the video as the camera moves side to side, up close and far back capturing different angles of the boxes.
I thought that the video was very random but still caught my attention thanks to the bright boxes and enteraining music. It was very stunning to see this type of animation.
