4/5. I bought this basically on the strength of seeing Kaufmann talk about his thoughts on Carlo on YouTube, and also the auto-da-fe scene shown in this link (at around 13:40) where Hampson's Rodrigo is all but trying to telepathically yell to Carlo DON'T DO IT!! And it is great, although I definitely imprinted really heavily on the Met 2011 Alagna/Poplavskaya/Keenlyside/Furlanetto so that it took me a while to warm to it sometimes.
( Don Carlo: it is awesome. Carlo/Rodrigo, Rodrigo/Filippo, Rodrigo & Elisabetta. )
