I got the Sieghart / Arnhem recording of this, which for some bizarre reason is issued on a Japanese vanity-press label. It comes with the usual booklet plus a foldout with two dozen parallel examples in score comparing selected brief excerpts of Samale / Mazzucca with Cooke 1975, which they seem to have taken as their starting point. The booklet includes eight pages of what looks like a Revisionsbericht keyed to the score examples and explaining them -- but it is all in Japanese, so although I can tell what it is, I cannot read it.
Can anyone suggest a musician who reads Japanese who could translate this, for appropriate compensation for their time? Failing that, is anyone aware of anyplace where Samale / Mazzucca have discussed their approach, either in English or Italian or German? I have not been able to find anything.
