I am so freaking lucky that I was able to score these tickets to sold out performances by Martha Argerich and Daniil Trifonov. (Argerich was sold out on the day box office opened!) I only learned about her recently - she is rated as #1 pianist! My mom, a piano teacher, did not know about her either but after I sent her some videos, she asked that I clap extra for her tonight. :) She will be playing with an Italian orchestra - which is extra fun for me. And it looks like there will be a live transmission of the concert.
I first saw Trifonov after he won the Tchaikovsky competition and also really looking forward to his performance.
P.S.: Look at this photo of Martha Argerich from 1971. She is such a feline!
