Light shows have practically become passé with the influx of trippy Pink Floyd shows and art installations with interactive lighting designs. But before all of this was the case, there was Iannis Xenakis. Trained as an architect directly under Le Corbusier in the 1950s, the Greek-French composer would eventually become best known for his music. The student had also recorded some conceptual-classical music earlier in the decade, and when his training with the legendary architect ended, Xenakis put the two disciplines to use.

The outcome was "polytopes," or big, media installations combining light shows with musical scores. He staged them in holy grounds, such as churches, and even as early as the 1960s and 1970s used computers to program the two mediums to engulf event goers in a new sensory experience.
