I have not seen much recently regarding Animusic type of animations. To be fair, those animations, as impressive as they were at the time, are a bit outdated today in terms of the rendering and musical reproduction (being mostly midi - or synthesizer - based). That is why I thought I would share this site:
(2635) Marvin Blend - YouTube
He does have a tutorial on how to start making these animations in Blender
The music and the animations are very impressive and just fun to watch and listen to.
Enjoy,
Dave
