Iannis Xenakis - Metastasis (Spectral View)

Metastasis is an experimental music composition written for orchestra in 1953 by the Greek experimental composer Iannis Xenakis. I have always thought of his compositions visually, almost as if they are unfolding alien landscapes. This spectral view of the music timed exactly with the music illustrates that idea perfectly. This is another that I would suggest watching fullscreen.
