In 2012–2013, using the surviving vocal score, Langer re-orchestrated César Cui's 1913 opera Puss in Boots (Кот в сапогах) for the Grand Théâtre de Genève, for performance in May 2013.
Her song-cycle for soprano, counter-tenor and baroque chamber ensemble, Landscape with Three People, based on poems by Lee Harwood, was performed at Concerts at Cratfield in August 2013.
[9] In 2014 Shakespeare's Globe commissioned incidental music from Langer for David Eldridge's play Holy Warriors, about the 12th-century struggle for Jerusalem, during the Second Crusade, between Saladin and Richard the Lionheart.
[10] In 2015, in response to a commission from the Britten Sinfonia for an orchestral piece, Langer wrote Story of an Impossible Love, which was performed in Cambridge and London in 2016, and subsequently in Calgary and Karlsruhe, where it was conducted by Justin Brown.
The opera subsequently toured around the UK and in 2017 was performed at the Teatr Wielki in Poznań and at the Grand Théâtre, Geneva, with a live stream on the Arte Channel in Switzerland.
Besides the title track the CD also contains Ariadne, Elena's first collaboration with Glyn Maxwell, and the light-hearted Cat Songs, based on the absurdist poetry of Daniil Kharms.
[15] With a libretto by David Pountney, Langer's next piece, Beauty and Sadness, a chamber opera based on the 1964 novel by Yasunari Kawabata, was premiered at the Lyric Theatre, Hong Kong Academy for Performing Arts, in April 2019, directed by Carolyn Choa, designed by Tim Yip and conducted by Gergely Madaras.
