When I saw the opera on Saturday, it was neither Moses nor Aron who grabbed my attention. It was the Israelites, played by the hugely impressive WNO chorus. United in praise for Moses, their voices reached a pulsing spiritual ecstasy; when they hound Aron, they are invigoratingly angry. Schoenberg clearly saw the dangerously fickle nature of humanity, especially when as a collective force. (Remember this is when the Nazis were starting to manipulate the masses). We can see the attraction of the voice in the wilderness, railing against our moral corruptions. The difficulty comes in telling the true prophets from the false ones.
