Edward Gardner is the English National Opera’s new music director. “The conductor Oleg Caetani was to have started as music director this month, but resigned at Christmas even before he began. The company has, since November, also lost an artistic director and a chairman. Gardner is music director of Glyndebourne Opera’s touring arm, and a former assistant at the HallĂ© Orchestra to Mark Elder, who himself was 32 when he became music director of ENO in the 1980s.”
