From the very first moment she took the Grammys stage, host Alicia Keys made it clear the night would be about paying tribute to music.
And it was Keys herself who delivered one of the most powerful performances of the night - with a medley that included classics from five different decades.
Sat between two pianos, the 38-year-old songstress wowed the audience at the Los Angeles Staples Center on Sunday as she began to play them both at the same time.
Singing sensation: Alicia Keys delivered one of the most powerful performances of the Grammys as she took the stage with two pianos, which she played at the same time
'I've been thinking so much about the people and the music that have inspired me, and I want to give a shout out to Hazel Scott because I always wanted to play to pianos,' she said, referring to the late jazz pianist and movie star.
'You know those songs that live inside of you and live inside of me, and you just love it so much, because it was done so well that you wish you wrote it?'
'That's how I feel about these songs. I wish I wrote them.'
Keys first began with the song that she said she thinks about when she reflects on 'heartache and heartbreak', playing Roberta Flack's 1973 tune Killing Me Softly, later popularized by Lauryn Hill and The Fugees.
'Or when it's time to move on, this is the song,' she said, breaking into Juice World's recent hit Lucid Dreams before switching to Nat King Cole's 1952 classic Unforgettable.

'Now, who didn't wish they wrote this song? I know I do,' she said as she began singing Kings of Leon's 2008 hit Use Somebody.
That turned into In My Feelings, Drake's song of the summer, and Boo'd Up by Ella Mai before Keys began playing Doo-Wop (That Thing), saying she wished she had written the entire Miseducation of Lauryn Hill album.
'Then, finally, you write the song you wish you wrote,' Keys said before she broke into her own tune Empire State Of Mind.
Keys' medley was an instant hit on Twitter, with many calling it the best performance in a Grammys that had already been praised throughout the night.

'Okay but who is doing it like Alicia Keys she literally has more stage presence than half the industry and she's only up there with two pianos,' one fan wrote.
'Alicia Keys is refreshing everyone's memory on why she's one of the greatest of all time,' one commenter wrote.
'When the best performer of the night is also the host. #GRAMMYs @aliciakeys,' another added.
Ana Navarro joked that Alicia Keys was doing such a good job she should 'just go ahead and host the Oscars too'.
Many said they would've been happy to keep watching Keys perform for the rest of the night
'God exists and loves us, and the proof is Alicia Keys,' quipped Ben Domenech, while on fan added: ' I don't know if there is a God, but if there is, she listens to Alicia Keys.'
Many said they would've been happy to keep watching Keys perform for the rest of the night.
'The @aliciakeys two piano medley was the best thing on tv tonight, this week, probably for a very long time,' one fan wrote.
'I could have settled in for a whole Alicia Keys concert after that performance, didn't want it to end,' another added.
Billy Eichner was among the many who also praised Keys' hosting abilities during the night
'Give me Alicia Keys and 2 pianos the rest of the night and I'm good,' one viewer quipped.
'I'm the epitome of non-target market of Grammys. You know what, I'll tune in every year if @aliciakeys hosts and does a 20-minute riff of everyone's best songs,' added Paul Kane.
Many marveled at Keys' ability to host the show with ease and then pull off an incredible performance, which some suspected was actually a filler after Ariana Grande pulled out of the show last minute.
'Alicia Keys is a godsend. Most folks have no idea what a heavy lift it is to host a show of this magnitude. Then to straddle two pianos and belt out a complication performance of, what, 7 or 8 songs? Simply. Amazing,' one fan wrote.

'Music is what we cry to. It's what we march to. It's what we rock to. It's what we make love to. It's our shared global language, and when you really want to say something, you say it with a song, am I right? Or am I right?'
Later in the ceremony, Keys welcomed Michelle Obama onto the stage, with the former First Lady stunning the star-studded audience as she joined a plethora of female singers beneath the bright lights.

'Music helps us share ourselves, our dignity and sorrows, our hopes our joys,' she continued.
'It allows us to hear one another - to invite each other in. Music shows us that all of it matters...every story within every voice, every note within every song.'

Earlier in the evening Lady Gaga was emotional as she earned Best Pop Duo/Group Performance for her work on Shallow from the A Star Is Born soundtrack.
The emotional high point of the night happened as Cardi looked absolutely stunned as she won in the male-dominated category beating out Pusha-T, Travis Scott, Nipsey Hussle, and the late Mac Miller.
Cardi seemed overwhelmed as she received her honor as she joked: 'Oh, the nerves are so bad. Maybe I need to start smoking weed!'
Obviously taken aback by the moment, Cardi had to hold the hand of her Migos member husband, Offset, during her speech.
Daring: Travis Scott put on a very impressive performance as he jumped off as metal cage while singing No Bystanders
It was a show of support amid the marital issues they have had over the past year as the 27-year-old rapper even kissed her hand during her acceptance speech.

'He was like you're going to do this album,' she said of Offset. 'We're going to have this baby and do this album.'
Cardi B is just the fifth woman ever nominated in the category, which was created in 1995. Lauryn Hill was part of the Fugees when the group won in 1997 for The Score.

Gaga urged the audience to be more compassionate when it comes to mental health issues as she said: 'If you see somebody that’s hurting, don’t look away.
'If you're hurting, even though it might be hard, try to find that bravery within yourself to dive deep and tell somebody.'
The New York-native was already a double winner as earlier in the night she earned Best Pop Solo Performance for her album Joanne.
It was also A Star Is Born's second win of the night as earlier they were announced as the winners in the Best Song Written For Visual Media category.
