Yeah that's mostly masking. Using the mask/pen tool they would cut out the character and then add it on top of a different background.
The flashes on certain beats are simply a white solid inserted in the timeline for only a quick frame or 2 in length.
As for the backgrounds it looks like they may have been pulled from spots in the animation and used to create and effect like spectacle. If it were done in Vegas or After Effects it would look more computer generated than that. Some of them may be (like the animated circles moving forward) but most of them appear to be Avatar source footage.
