Hans Perk has posted another piece of animation accompanied by a click track. This time, it's the Mickey Mouse cartoon, Thru the Mirror. Hans has taken the beats off the original bar sheets and put visual and audio beats over a copy of the film.
Take a look at it soon, as YouTube has been fairly aggressive lately in removing copyrighted material. Clearly, this is not an attempt to rip Disney off, this is an attempt to explain the studio's work processes and educate a new generation of animators.
(Mike Sporn beat me to linking to this, but it's so important that it deserves the redundant link.)
