Soul singer Adele triumphed in her return to the stage last night, scooping up six Grammys and winning every category in which she was nominated.
The 23-year-old underwent surgery on her vocal cords late last year and had been resting her voice on doctor's orders until music's biggest night.
For the first time since then, she belted out Rolling In The Deep and finished to a standing ovation.
The singer, with tears in her eyes, had difficulty speaking as she took to the stage to claim the night's top award, album of the year. "This record is inspired by something that is really normal and everyone's been through it, just a rubbish relationship, and it's gone on to do things I can't tell you how I feel about it, it's been the most life-changing year."
Rockers Foo Fighters were the other big winners, picking up five Grammys including best rock performance for the hit Walk.
Other big winners included country's Taylor Swift, who picked up Grammys for solo performance and country song with Mean, which she performed to a standing ovation. She had been expected to take best country album, too, but Lady Antebellum swooped in and took that prize with Own The Night.
The other big surprise came when indie folk band Bon Iver took the Grammy for best new artist over rapper Nicki Minaj, who had been widely expected to win for her hit album Pink Friday.
Jay-Z and Kanye West won best rap performance with their song Otis from the album Watch The Throne, but they failed to show up to claim their prize. Chris Brown won the Grammy for best R&B album F.A.M.E.
Rousing performances were given by Bruce Springsteen and the E Street Band, Chris Brown, Coldplay and Rihanna, Jason Aldean and Kelly Clarkson. Alicia Keys and Bonnie Raitt sang a duet of A Sunday Kind of Love from Etta James, who died recently.
Minaj gave fans an over-the-top performance and Paul McCartney ended in a guitar-heavy number with Springsteen, Grohl and others. Memorable moments came in a reunion of the Beach Boys and a lifetime award for Glen Campbell.
