He Break Dances. He Pole Dances. He Sings Like an Angel.

The Polish countertenor Jakub Jozef Orlinski has the credits you’d expect for a fast-rising classical music star, and some others you might not.

LONDON — When foreign stars visit the Glyndebourne opera festival in the countryside outside London, it’s common for them to participate in some time-honored English rituals, like sipping Pimm’s on the lawn or nibbling on a scone for afternoon tea. But when the young Polish countertenor Jakub Jozef Orlinski arrived to perform the title role in Handel’s “Rinaldo” in 2019, he announced his presence differently: by break dancing on the terrace in front of an audience in ball gowns and tuxedos, as well as a photographer or two.

Judging by Orlinski’s Instagram account — 123,000 followers and counting — this wasn’t an isolated incident. To promote his Metropolitan Opera debut in Matthew Aucoin’s “Eurydice” last fall, he flexed his breaking skills in Lincoln Center’s plaza, and the company’s publicity team filmed it in slow motion. During a recent stint at the Royal Opera House here, Orlinski posted a picture of himself on that hallowed stage doing a so-called Slav squat (if you’re over 30, Google it) with the hashtag #LetsBarock.

“Dude, these pics are so FIRE,” one commenter wrote.
