Who Will Have the Biggest Grammy Night?

The 66th annual Grammy Awards on Sunday are poised to be a celebration of a dominant year for women in pop music, with female stars like SZA, Taylor Swift, Olivia Rodrigo and Billie Eilish facing off in the major categories.

SZA, whose “SOS” was a critical and chart smash, leads with nine nominations; the pop and R&B singer and songwriter Victoria Monét has seven; and Swift, Rodrigo, Eilish, Miley Cyrus and the indie-rock trio boygenius have six apiece. Swift and SZA each have the potential for landmark wins.

For an award show that in the past has been criticized for its treatment of female stars, its lineup alone is being interpreted as a sign of progress. But the show this year is taking place in the shadow of lawsuits against two former Grammy leaders, accusing each of sexual assault. Neil Portnow, a former Recording Academy president, has denied the allegations against him; Michael Greene, his predecessor, has not commented.

Never bet on the Grammys’ being too predictable. Industry politics, vote-splitting and a shifting membership have the potential, as always, to scramble outcomes, despite expectations about who may win or lose.

Whoever wins, the night will have a roster of performers that mixes young and old, fresh faces and classics, including SZA, Eilish, Rodrigo, Joni Mitchell, Luke Combs, Dua Lipa, Travis Scott, Burna Boy, Billy Joel and U2. The host, for a fourth straight year, is the comedian Trevor Noah.

Here is a look at some of the night’s major story lines.

Will Taylor Swift Make History?

Swift was a gale-force power in pop culture last year, and she has the potential to make a major mark at the Grammys.
