Zubin Mehta has recorded a few versions of Turandot. Roon has a false equivalence between his version with Joan Sutherland and Luciano Pavarotti and his version with Jennifer Wilson and Andrea Bocelli.
the Verdi Requiem is an odd recommendation (Manon Lescaut makes sense). it might fit if that particular version included any of the same artists, but it doesn’t.
also, Bocelli has no business singing Calaf.
