At a concert hall in western Ukraine, a classical music programme resurrecting lost and neglected works of Ukraine's repertoire is packing the house nightly, often featuring a resident orchestra that fled the war zone. Air raids occasionally interrupt the concerts, and musicians have played by candlelight during power cuts, but the Organ Hall in the city of Lviv - in a stately 17th century former Catholic Church - has become one of the hottest tickets in town. Performing during the war means tighter budgets, longer hours and quadruple the effort, said the hall's co-director Taras Demko.
