ON WITH THE SHOW: THE MUSIC, THE MOMENTS AND MORE

And we're off. Lizzo starts the show. "Tonight is for Kobe," she says, and the line "I'm crying, 'cause I love you" takes on new meaning. A ballet interlude takes us into "Truth Hurts." It's an energetic intro as the toss goes to host Alicia Keys. "We're all feeling crazy sadness right now," she says, addressing the obvious. "We're standing heartbroken right now in the house that Kobe Bryant built." She asks the crowd to hold them in their thoughts. Then she's joined by Boyz II Men for a vocal tribute; nearly every face in the crowd is streaked with tears. Then some words about the healing power of music. Keys had an unenviable task, opening the task on this sorrowful note, but she did so with grace.

Next comes a Blake Shelton/Gwen Stefani duet, "Nobody But You."

"Real talk, there's a lot going on," says Keys, seated at the piano. "I'm proud to be here as an artist for the artists," she adds, adding the importance of "inclusivity." Shout-outs for Billie, Lizzo, Ariana. "I know how much Kobe loved music, so let's make this a celebration in his honor." Then a little survey of artists to the tune of "Someone You Loved."

Billy Porter takes the stage and brings the mega-energy and the blue eye shadow, introducing the Jonas Brothers, who deliver a footloose performance of "What a Man Gotta Do."

Keith Urban and Cynthia Erivo step up to give the Best Pop Solo Performance trophy. Lizzo takes it for "Truth Hurts." "All my problems that I thought were big as the world were gone," she says, calling on the crowd to make music "that liberates people."

Trevor Noah strides out to introduce Tyler, The Creator (joined by Boyz II Men and Charlie Wilson) on "Earfquake," and then an army of bewigged Tyler clones marches up to assist him on the freaky "New Magic Wand." The chaotic energy suits the tenor of the moment more than anything else so far.

A glittery Shania Twain and Bebe Rexha give away Best Country Group/Duo Performance, which is won by Dan + Shay. Jason Owen and Scooter Braun get a shout-out.

Usher leads a spirited Prince tribute, with Shelia E. on drums. He romps through "Little Red Corvette," "When Doves Cry" and "Kiss," with his impressive moves on display. The Grammy tribute show to Prince, which tapes on 1/28, will be broadcast on CBS, date TBA. Beck, Keys, John Legend, Coldplay's Chris Martin and Juanes are among the scheduled performers.

Camila Cabello sings the intimate "First Man" right to her weeping dad, accompanied by some home video. Don't pretend you didn't get weepy there, you sentimental fool.

Tanya Tucker sings "Bring My Flowers Now," which has already won a trophy, accompanied by co-writer/producer Brandi Carlile on piano. Then the pair, incongruously, gave away Comedy Album, which is won by Dave Chappelle.

Ariana Grande takes the stage for a medley; an orchestra backs her up on "7 rings," and its source, "My Favorite Things," and then "thank u, next."

Keys brings out Billie Eilish, joined by FINNEAS on piano, for "when the party's over." You could hear a pin drop.

MusiCares honorees Aerosmith perform "Livin' on the Edge" and then reunite with Run-D.M.C. for the groundbreaking "Walk This Way." It's chaos, but Lizzo's really digging it.

Issa Rae of Insecure comes out to bestow Rap Album. It's Tyler! He jumps up, joined by his emotional mom. Reaction shots from Rob Stringer and Ron Perry. "I really wanna thank Pharrell Williams," he says. "That man allowed me to be comfortable with myself."

Ellen DeGeneres brings out Lil Nas X, joined by Billy Ray Cyrus, BTS and Mason Ramsey.... and "big" Nas. It's a big production number with multiple sets.

Introduced by Greta Gerwig, an overwhelmed Demi Lovato launches into her new song, "Anyone." It's one of the most powerful moments of an already emotional evening. Standing O.

Keys and Dua Lipa prepare to bestow Best New Artist, which both have won in the past. It's Billie, who gives it up to "all fandoms."

A nice moment for Ken Ehrlich at the end of his 40-year run. John Legend pays tribute. Rather than go onstage, he offers a Grammy moment tailored to music education in the schools: "I Sing the Body Electric" from Fame. Cabello comes out first, then Cyndi Lauper, then Broadway star Ben Platt and duo The War and Treaty. Gary Clark Jr. contributes a guitar solo. Common spits a few bars.
