A couple of things to mark the centenary of Iannis Xenakis, whose remarkable life is summarised in the following Guardian guide to his music, although the film – in French, w/ English subtitles - has more on his architectural, electronic & multimedia works:
https://www.bbc.co.uk/programmes/m0017m17 (36:25 - 53:35) [...] a performance of his work for harpsichord and chamber orchestra, "A l'île de Gorée" [...]
***flashing lights / strobes*** are used in the film’s second half (especially during the percussion pieces & the first two tape pieces that follow them – please see below for their approximate start times). This is from https://manifeste.ircam.fr/agenda/polytopes/detail/: “Warning: The performance Polytope has been identified as a potential seizure trigger for people with photosensitive epilepsy (strobe or flashing lights)”

Xenakis Revolution: The Architect of Sound [...] a fascinating portrait of the composer, engineer and architect Iannis Xenakis (1922-2001), a leader of the avant-garde and a pioneer of sound and light shows, who turned contemporary music upside down by bringing art and mathematics together.
