'Making music is a bit like cooking. If you follow a recipe for a certain cake, it will, if the ingredients and the oven temperature are correct, turn out more or less the same each time you do it. So maybe one day you put in a few almonds or a squeeze of lemon, perhaps you do something else a bit different – imperceptible changes that can make a great cake into an amazing cake. In music, you don't always follow the same recipe. It depends how you feel in the moment – you might want to make a tiny right turn instead of a left. Surprising things can happen if you don't always pick the same direction.'
