Philip Langridge, an English tenor known for his roles in Britten operas, has died at the age of 70. His most recent appearance was in the unusual role as the Witch in Humperdinck's Hansel und Gretel at the Met, but Mr. Langridge leaves a legacy behind with renowned appearances in the operas of Mozart, Janacek and Stravinsky. He was a sublime interpreter of Schubert and Bach, and became a champion of Harrison Birtwistle. The New York Times has a remembrance here and the BBC has one here.
