An Irish princess falls in love with the wrong man on her way to be married in Cornwall. The story, steeped in Celtic mythology, is tragic, but Wagner’s score is gorgeous, especially in the hands of Zurich Opera Music Director and frequent collaborator Fabio Luisi. Haydn’s grand “London” Symphony opens our British Isles farewell. When Haydn left Vienna for England, he left behind a promising young pupil, 23-year-old Ludwig van Beethoven, who soon went on to write a few memorable works of his own, including the timeless Piano Concerto No. 3, heard here with legendary soloist Yefim Bronfman.
