O2 Arena, London

The ambition of 2025 album Lux is scaled up even bigger by the Catalan megastar, delivered with operatic vocals and en pointe ballet moves as well as funny asides and glasses of wine

rapped in a vast white sheet, Rosalía is telling the audience a story about her youthful dreams of performing in London, undaunted by the fact that her English is, as she puts it “a little bit rat-a-tah”. It turns out her real ambition was to sing at the Royal Albert Hall – “which I’ve never done” – but no matter: “I have sold out two nights at the O2!” she cries triumphantly. “Crazy, crazy,” she adds, shaking her head.

You can understand the Catalan singer’s surprise. We are supposed to live in a hopelessly risk-averse era for pop, where what audiences are deemed to want is more of the same. While you might have expected her fourth album, Lux, to be greeted with critical hosannahs, the fact that she’s managed to fill one of the UK’s biggest venues twice off the back of a song cycle based on the lives of various female saints, sung in 13 different languages, and set to music that conjoined lavish orchestration with leftfield electronica – and provoked a debate about whether the results should be filed under classical rather than pop – seems pretty improbable.
