on one hand you have demonstrated the exceptionality of the event, the fact that it was advertised as an incredible and unmissable cycle (the performance mode "opera omnia" would truly deserve a doctoral thesis in sociology), that the thing took place over 9 years (crazy), with the declared and essential participation of one of Europe's wealthiest cities (Milan) and within a CHAMBER season. But I never admit to being wrong, so it is I who am using rhetorical stratagems at this moment ehehe
anyway, really, if we take the discussion in a less orthodox way, we immediately understand how there are genres in music history that today 1) are not successful 2) constitutionally cannot be performed in the same way they were performed (and conceived) in the past 3) and even when they could be performed in that way, they are still "adjusted" (in dimensions, above all, but also in instrumentation, in structure) 4) and, consequently, lose meaning when coming into contact with our current performance world. The widest repertoire on which these problems are visible is that of sacred music. 1) masses are not successful 2) they are difficult to perform as part of a true liturgy with stable and specialized instrumentations 3) much more often they are compressed and performed in concert mode, or parts of them are performed 4) and, consequently, they become ARCHAEOLOGY, that is, rediscovered music, musealized, protected
