Here are a couple of videos I’ve recently enjoyed. Visually intense material not for those who get dizzy easily.
Aphex Twin did a ‘Pendulum set’ back in 2011 in Poland. This was a piece originally composed by Steve Reich in 1968. Progressing on this a bit, the mics used in this set were outfitted with mirrored disco balls and used to create a hypnotic matrix of kaleid-a-scopic laser like beams swaying with the rhythm of the swinging as it naturally slowed during the process.
This next video is by Toshio Matsumoto who I know very little about, though I have heard of Funeral Parade of Roses (1969) which apparently was influential on A Clockwork Orange. This video is abstract and very psychedelic and challenging (in a good way) to watch. The music was done by Toshi Ichiyanagi who was involved with The Fluxus movement and studied with John Cage as well. Enjoy the trip!
