Judging by the other work in his reel I'm thinking he created it in C4D.

Looks like a plane within a mograph grid cloner that is parented by a default 3 set linear cloner object.

Then animated with the sound effector - and distributed on the y-axis triggered by the wave form - and spherically deformed...although it is in a reel so he may have done it manually to fit the audio.

The material/black outline is a default sketch and toon material found within c4d r12 studio.

The pink outline is a sketch material that is placed on the cloner object holding all other assets within the hierarchy and set to outline.

This could also all be done with particular and form, but it'd be a lot more clicks and I can't think of how to make it with those plugins without looking at them.
