There's a 3D deformation happening here, along with an optical glow on the bass beats.
I would guess this was made in After Effects, using the plugins Trapcode Form or possibly Plexus with Sound Keys applied to a deformer using the bass in the music. Then an Optical Glow added which gets more intense using the same keyframes from the bass.
