Indonesian jazz pianist Joey Alexander is the youngest performer ever to be nominated for the prestigious music award.
He did not win a Grammy but while the young musician performed on stage, the cameras panned across to singer Bruno Mars, who was watching with glistening eyes.
Many from Joey's homeland also expressed their admiration and support for the young star.
You were definitely the star of the show," tweeted Indonesian music composer Sherina Sinna. Movie-maker Joko Anwar also described him as a "hope".
Josiah Alexander Sila was born in Bali's Denpasar city to Christian parents Denny Sila and Farah Leonora Urbach, who ran a tourism business.
His parents have described their son's talents as a "gift from God".
There were no formal jazz classes in Bali where he grew up, so the young musician took part in jazz sessions with more experienced performers.
It was then that his parents decided to make the move to the Indonesian capital Jakarta - home to one of the world's largest jazz festivals - to pursue Joey's musical dream.
He went on to win music competitions before his family moved to New York in 2014.
The child prodigy taught himself to play piano at age six, after his father bought him an electronic keyboard.
Joey has said that learning music came naturally for him, thanks to listening to songs from his father's personal jazz collection.
"My dad played a little bit of piano and guitar, but not that professionally," Joey said in an early interview, about falling in love with the piano.
"I saw him play and I said, 'I want to play. I want to try this instrument.'"
The young musician considers Harry Connick, Jr. and Herbie Hancock among his main musical influences, and also admires Clifford Brown and Miles Davis.
There could be something in the blood because he is also the nephew of Indonesian rock singer Nafa Urbach.
Renowned Jazz trumpeter Wynton Marsalis, discovered Joey after seeing him perform in a YouTube video in 2014.
Praising the young pianist on Facebook, he then invited him to play at the Jazz at Lincoln Center's gala, making him him an "overnight sensation".
Joey went on to make his US debut, performing at several Jazz festivals.
Joey's debut album titled, "My Favourite Things" was released on 12 May, 2015. He was 11 years old at the time of its release.
He  became the first Indonesian act to crack the US Billboard album charts, debuting at number 174.
The record re-entered the charts and peaked at number 59 in January 2016.

The coins, which are known as Scottish groats, were discovered by keen metal detector Tom Crawford last January.
They were buried about eight inches beneath the soil on a farm near Banbridge.
Experts believe they are part of a larger hoard of coins found by Mr Crawford in the same field in 2001.
The collection was probably dispersed over time through ploughing.
This was Mr Crawford's fourth time at a treasure trove inquest.
He said his success was about "knowing where to go" and "having a fair idea of where to look".
"There is more chance of finding something where you know people would have been living 1,000 years ago," he added.
He said discovering long-buried artefacts was a "euphoric" feeling.
"It's not so much the money, it's the fact that you are the first person to touch something in 700 years," he said.
"I found a 3,000-year-old bronze axe about 10 years ago and it's the idea that something has been hidden for so long and then you get to see it and touch it."
Former curator at the Ulster Museum, Robert Heslip, said the hoard of coins was probably buried near a landmark - a small Rath ring fort.
The person who left them may have died before reclaiming them.
He said finds like this one are significant because they are specific to a particular time and to this part of Northern Ireland.
"You find virtually nothing like this in the south of Ireland and they peter out in the west," he said.
"There have been a cluster of these sorts of finds in eastern Ulster."
The coins will now be sent to the British Museum in London for valuation.
It is thought they are probably worth between Â£50 and Â£100 each.
They will be offered for sale and any profit is split between the finder and the owner of the land where the treasure was uncovered.
He may be only 11, but he delivered a performance that brought the audience at the 2016 Grammy awards to their feet in a standing ovation.
