Haven’t done a music-related post in a while. I’m not entirely sure that this counts. Here’s a blast of György Ligeti’s Symphony for 100 Metronomes. (It doesn’t really get going until around the 1:00 mark, then brace yourself for some serious excitement.)
It seems almost impossible to describe this piece without the use of ‘sarcastic quotation marks’, but I think it’s ‘great’. If you happen to have 100 metronomes lying around why not have a go yourself with the score.
