I saw Anna Fedorova at the Concertgebouw this evening. Most of the concert was with Benedict Kloeckner on cello. The highlight was when they got ready to play the Piazzolla numbers she came out and said it turns out her page turner is an excellent double bass player and he was going to join them. I can't imagine they hadn't rehearsed that together but he never appeared on the program. They then performed the two Piazzolla pieces with the double bass player joining them for a trio and her turning her own pages (which looked adventurous a couple of times). It was a great show.
