Lady Gaga

Lady Gaga debuted a R&B-tinged love song Saturday as she headlined the Coachella festival, where the pop diva cast herself as glamorous rather than sensational.

The first woman in a decade to top the lineup at the premier music event, Lady Gaga unleashed an action-packed spectacle of acrobatic choreography that culminated in confetti, fireballs and fireworks on her dance anthem “Bad Romance.”

Gaga seized upon the spotlight to introduce a new song, “The Cure,” that is built off an unadorned R&B rhythm before rising into a pop chorus with the lines, “If I can’t find the cure, I’ll fix you with my love.”

She released the song commercially as she left Coachella in the California desert, marking her first new music since her latest album “Joanne” came out in October.

Coachella offered a preview of the global tour the pop superstar will launch in August for “Joanne,” an album that brought a more classic pop and even country sound to the 31-year-old artist long associated with synthpop.

Yet for a singer once talked about as much for her outrageous outfits as her songs, she stepped back and put the emphasis on her music — giving herself space to show off her glowing, rich voice on tracks such as “The Edge of Glory.”

Her biggest fashion message may have come as she played piano. She struggled to take off her sweater mid-song, in an endearing display of authenticity.

Lady Gaga played her first Coachella after original headliner Beyonce canceled on doctors’ orders as she expects twins.

One of the most lucrative events on the global cultural calendar, Coachella takes place over back-to-back three-day weekends with identical lineups.

In a Coachella hallmark, Saturday saw a slew of surprise performers — delighting fans who avidly posted to social media.

The rapper Future, who recently made history with back-to-back albums debuting at number one on the US chart, drew cheers when he brought to stage Migos, the Atlanta trio behind the hit “Bad and Boujee.”
