Bruno Mars and Kendrick Lamar stole the show, and most of the awards, at the 2018 Grammys.

Mars provided the night’s big upset, taking the album of the year trophy that most critics assumed would go to Lamar’s rap tour de force, Damn.

In the end, voters found Mars’s crowd-pleasing R&B more palatable, while Lamar dominated the rap categories.

Alessia Cara won best new artist – making her the only female artist to win a major prize.

Stars like Lady Gaga, Kesha, Lorde and SZA were overlooked, with only 17 awards (out of a total of 86) going to women or female-fronted bands.

The imbalance was particularly incongruous on a night that highlighted the #TimesUp and #MeToo campaigns.

Most performers arrived for the show wearing a white rose to symbolise their support for the movements, which tackle sexual harassment and inequality.

Pop star Kesha also gave a powerful, stirring performance of her single Praying, which addresses her own experience of surviving abuse.

She was backed by an all-star choir, including Cyndi Lauper and Camila Cabello, who were dressed in white to reflect the white rose campaign.
