Here are my The Beatles: Rock Band animated backgrounds.
They all have a decent number of frames, and they dont take much to load because of their resolution, 384x288, but they look good in-game despite the lowres.
I plan to do more of those, not from TB:RB only, so if you have any requests please ask!The Backgrounds
Those are all at the moment, but as I said, I'll make more.
Please let me know whatcha think of them.
