In this little test I used the Sound Effector in Mograph linked to the Z-Scale parameter for each bar. The song is an instrumental version of Metronomy’s Heartbreaker. I got the remix package of the song (every instrument as a separate track/file) and linked individual instruments/sounds to different bars (quite structured, compared to what I think is a semi-chaotic result).
The material on the bars is a mix of Subsurface Scattering, Ambient Occlusion, Mograph’s Multishader, and a hint of Reflection. If there’s one thing I learned, it’s that Subsurface Scattering takes a long time to render.
After that, some curves adjustment in After Effects along with a vignette and scanlines for effect.
