I am surprised there aren't more comments here. This is a lovely performance, technically perfect, and full of energy and love for the music. Brava and bravo!!!
NOT applauding in beteween movements is a relatively modern "etiquette". It was not a problem al all during Romantic era, for instance, specially in concerti were the cadenzza finalizes some moviment, and was seen more or less like the "open scene applause" after an aria in opera.
