A ruthless Russian leader quelling revolt and uniting his country through waging war on its neighbours: the theme of Sergei Eisenstein’s film Ivan the Terrible, intended as a Soviet propagandist parable, raises a knowing eyebrow even today. Excerpts from Prokofiev’s score formed the bulk of this raucously enjoyable concert by the Philharmonia under Vladimir Ashkenazy, beneath a screening of key scenes from the film itself.
