I have only just seen the discussion, but I do not agree at all with any of you.
Therefore, if you were looking for the devil's advocate, I will gladly play the part.
In the years of endless controversy regarding Allevi, I have become convinced (and the number of interventions in this discussion demonstrates this amply) that there is a decidedly hysterical attitude toward anyone who dares to propose light music for solo piano, especially if it is based on notation (and this is what, in modern convention, makes it defined as "classical"). Of course, regarding Baglioni, for example, no one will ever say anything bad about him here, because he doesn't write like Mozart did... he makes songs, pounds the notes, and that's that; the same goes for Bollani because "he does jazz anyway."
I read that Einaudi, Allevi, Bomoll, Mizzoni, would all be made of the same stuff... Are we crazy...?!? We are in a music forum, and it is assumed that these gentlemen musicians know the artistic currents of the twentieth century: one cannot confuse Allevi with Einaudi, Glass, Thiersen, and other post-minimalists; and I say without hesitation that whoever does so is an ignorant person who reasons with prejudice, who does not know how to distinguish one expressive mode from another.
Another thing that infuriates me is that, to support the anti-Allevi thesis of "I know they are all the same," Bomoll or Mizzoni are always brought into it, while highly respectable musicians with solid "classical" foundations like Giovanni Sollima, Licia Missori, or even Alessandra Celletti are punctually forgotten, or established session musicians like Giorgio Costantini (whom I don't like, but that's taste): people who nonetheless try to combine chickpeas with beans, as they say in Rome, while we pretend not to know that with the much-coveted "cultured" compositions you don't have the slightest hope of making a single cent.
Therefore: Is Allevi bad? Is Allevi wrong? Who knows.
Anyway, if someone wants to explain to me why we should still be sitting there nitpicking over the Adagio from Moonlight instead of Allevi's Nuotatore, I would be grateful.
