Yvonne Kenny when she replaced, with only four days' notice, the soprano scheduled to sing in an Opera Rara concert performance of Donizetti's "Rosmonda d'Inghilterra" at the Queen Elizabeth Hall. It was a triumph and the virtually unknown Kenny became an overnight star. She made her debut at the Royal Opera House the following year, in the premiere of Hans Werner Henze's "We Come to the River", later singing in Handel operas such as: "Semele", "Alcina", "Giulio Cesare", and such Mozart operas as: "Idomeneo", "Mitridate, re di Ponto", "La clemenza di Tito", "The Abduction from the Seraglio", "The Magic Flute". She also
Lisette Oropesa Cleveland; the St Matthew Passion in Chicago; "Abduction from the Seraglio" in Bellingham, Washington; and a reprise of her 2010 performance in "Le Nozze di Figaro" at Ravinia Festival. Opera engagements included Nannetta at the Dutch National Opera; Gilda at Grand Théâtre de Genève; and Konstanze at the Bavarian State Opera. Her last performance of 2014 was her debut at the Los Angeles Opera as Rosalba in Daniel Catán's "Florencia en el Amazonas". In 2015, she started the year at the Paris Opera as Konstanze with success "Oropesa, seguita da Marten aller Arten, cantata con accenti incisivi e appassionata recitazione."
