Simeon Ten Holt's "Canto Ostinato"

Over the last year or two I have listened to a lot of music that might best be described as "modern classical".  This has ranged from performers such as Hildur Gudnadottir and Julia Kent, using cellos, loops and electronics, to more conventional people like Agnes Obel or the stupendously great icelandic group, Amiina.  In each case, it is the combination of classical instrumentation and modern electronics that is the "modern" aspect.  And I guess all this would follow on perhaps from listening to lots of Arvo Part in the past.

Most recent "find" has been Simeon Ten Holt, a dutch minimalist composer.  His most well-known work is probably the "Canto Ostinato" which is a really long piece which can be performed in all sorts of configurations such as two pianos / two marimbas, or four pianos (there is even a version featuring an accordion).  It is in 106 sections, each basically at the same tempo but with significant variation and growing hints of discordance.

My favourite so far is a live recording for four pianos, or the version on Youtube that is accompanied by a strange video of pictures made out of stones.
