Lady Gaga Joins U2 on Stage at Las Vegas’ Sphere

The stars aligned at Las Vegas’ Sphere on Wednesday night (Oct. 25), as Lady Gaga joined U2 on stage for what turned out to be a mini set.

Dressed in a dark leather jacket, black tights and shades, Mother Monster was introduced to stage by Bono as “the most audacious, vivacious woman in any room she’s ever in,” Variety reports.

Sphere is no ordinary room. It’s a $2.3 billion, next-generation entertainment medium, with floor-to-ceiling graphics, thanks to nearly-580,000 square feet of fully programmable LED paneling — the largest screen of its type in the world. The images that have filtered back from U2’s residency are nothing short of mindbending.

Gaga came to play, and she dueted on “Shallow,” her Oscar-winning, Billboard Hot 100-leading number from A Star is Born, braced by two U2 classics, Rattle and Hum track “All I Want Is You” and the Joshua Tree hit “I Still Haven’t Found What I’m Looking For.”

It’s not the first time Gaga and U2 have come together to make sweet music.

Back in 2015, Gaga joined U2 at Madison Square Garden for a rendition of “Ordinary Love,” the rock band’s contribution to the soundtrack for the 2013 Nelson Mandela biopic Mandela: Long Walk To Freedom. On that occasion, the pop singer dueted with Bono and played piano.

Gaga is making something of a habit of teaming up with legendary rock bands from the British Isles. Last week, Gaga took the mic during the encore of the Rolling Stones’ intimate show at New York City’s the Racket, for a performance of “Sweet Sounds of Heaven,” the collaborative track lifted from the British band’s 26th album released in America, Hackney Diamonds. With a little help from Gaga, Hackney Diamonds led the midweek U.K. albums chart by a country mile, by outselling the rest of the top 10 combined.

Bono & Co. wrap up their 25-concert U2:UV Achtung Baby Live run in December.
