One of the most unusual albums from the 70s minimalist scene – a set that features different tracks with cyclical passages of instruments layered over one another – but with a vibe that's sometimes a bit more chaotic than similar work by artists like Terry Riley or Steve Reich! That quality is intentional, clearly, and the proceedings veer into noisier territory at times – with instrumentation played by the composer on most tracks, with help from a few other percussionists at points – in a shifting lineup that includes lots of glockenspiel, plus bass, piano, violin piano, percussion, electronics, guitar, and other instruments too. Titles include a number of variations on "Error System" – plus "Water Systemised", "Venezuela 2", "Bolivia", "Ecuador", and "Guitar Systemised". CD
