This critic forgets tha origins of opera. It began as a working class form of entertainment, often done outdoors.
The "heroic" style of singing, and the tremendous voices, that we associate with opera originated with the need for the cast to be heard outdoors with no amplification in those days.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
