It has been a bracing start to the year at English National Opera. David Alden’s production of Peter Grimes, praised to the skies for the musical performance under Edward Gardner, returned to the Coliseum. Next up is Rigoletto (reviewed on page 50), directed by Alden’s twin, Christopher. Then comes Rodelinda, in another new production (or co-production, as is often the way these days) by Richard Jones.
