20 minutes? my copy (bought the week of release) clocks in at 44 minutes long.
I love everything Carsten Nicolai's ever done - so much so that, like with other all time favorites, I consciously try not to play the releases too much so that I don't wear them out...
don't actually care for Sakomoto much. even his contribution here, although fits in
and contrasts beautifully with the clicks n bass, feels very sentimental. the kind of sentimentality that would be entirely intolerable if not for the context.
another very strong digital / piano collaboration, which I sometimes enjoy more than Nicolai/Sakomoto, is Taylor Deupree with Kenneth Kirchner. also on their second outing - the piano tones are more minor-key and abstract, the computer parts more unpredictable.
