Where I live they are a plague: Mozart's complete string quartets, Beethoven's complete sonatas and so on. I have not been to a concert in years! Maybe it is because the performer does not need to think. Alexander's programme and Eddy's future selection for a concert have this in common: you give thought to what you want to play, you try to match the pieces. I always believe in a "master programme", that is, a theme for the concert, this way one has a unity but in this unity, variety. I will give an example: Water. You create a programme that centers around music inspired by water, so, what do you have: Chopin: "Raindrop" Prelude Lizst: Les Jeux d'Eau à la Villa d'Este Ravel: Jeu d'Eaux Bortkiewicz: Etude "Fontaine Lumineuse" And so on.
