I have never been to the Verbier festival before but looking through the programme has been thrilling. Almost every concert made me think can I go for that one or this one. How about Martha Argerich playing Prok 3, Joshua Bell and Ravi Shankar playing together, Evgeny Kissin doing two solo recitals, Rene Fleming, Heinrich Schiff and Sarah Chang in one concert. It's just amazing.
