Such a loss for the opera world. To be honest, I prefered Domingo's sound, but there is no question that Pav was the standard to be judged by when it comes to Tenors. In incredible talent and an interesting character.
I had a coach that worked at the Met for several decades (he passed away last year, sadly), but he used to tell all sorts of stories about these famous singers. He told me one about Pav throwing a temper tantrum because there wasn't a piano in his hotel room once. Afterwords he sat down shaking his head and said "I ask for so little!" It loses something without the dramatic delivery, but it was funny to picture. He knew what he wanted and didn't except anything less. A force to be reconded with on many levels. Truly sad news.
