Practising my scales while BBC4 talks to itself in the background and then it is the ISIS or whatever it's called this week, knocking down statues, sculptures and buildings that had been there for the best part of four thousand years -and then I turn the volume up to hear some East London man praising these actions as 'destroying idolatry'. Depressing. They have done far worse in terms of human suffering, but destroying the cultural heritage of a people -no, of the world- is an unspeakably terrible thing with lasting consequences. Cannot think what really could be done about it. It's heartbreaking.
