English National Opera’s sparkling production of the much-loved Gilbert and Sullivan classic, set in the Tower of London of the 1950s.

A team of scientists becomes trapped in the frozen Arctic wastelands. Tensions rise and relationships crumble, and then something appears, out of the ice. This fourth collaboration between composer Stuart MacRae and librettist Louise Welsh is their most ambitious to date. With unrelenting drama and superb storytelling, Anthropocene engages with the crucial issues of our time – climate change, sacrifice and our ceaseless quest for knowledge.

Philippe Jaroussky as Ruggiero is in thrall to Patricia Petibon as the sorceress Alcina in Katie Mitchell’s virtuosic production of Handel’s opera from the 2015 Aix-en-Provence Festival, described by Bachtrack as “a night of a thousand delights”. Conducted by Andrea Marcon, this was, in the words of Opera News, “musically … a performance of the highest festival level”. The production of Alcina, by the British director Katie Mitchell, was welcomed by the Financial Times as “meticulously executed …, rich in detail, consummately polished”. As the New York Times wrote: “It involves a huge sorcery machine for turning people into animals (or whatever). And Ms. Mitchell works magic of her own onstage, constantly showing the enchantresses Alcina and Morgana alternating between glamorous public personas and their ‘real life’, older, private selves …There are also bits of simulated sex, mingling genders and suggesting, among other things, inventive new ways to hit high notes.”
