One Dutch pianist, Jeroen van Veen, seems to be obsessed with this work. He performs it constantly, alone or with others, and has just released a box set of his recordings, Canto Ostinato XL. This set contains 12 (!!!) recordings of the work, for one piano, two, four, and a variety of other keyboard instruments. To be frank, you don’t need twelve recordings, but given that you can buy this set (by download) for roughly the price of one or two versions, it’s a bargain. The set contains mostly one-disc versions of the work – less than 80 minutes – but the version for four pianos is nearly two and a half hours. I’d say the essential versions on this set are the first three: for one piano, for two pianos, and for four pianos. The music is very different with different numbers of instruments.
You probably won't want 12 versions of Canto Ostinato, but for the current download price (£8 at the time of this writing), it's worth getting this set for the first three versions alone.
