How can they sound like a whole choir. Damn these guys have ranges

Their unison is so perfect, it's crazy.

I do masterclasses with these guys all the time! They constantly visit at my performing arts school and are truly the nicest human beings, and also incredibly talented!

Why does it sounds like it's a whole choir singing? It's so cool!!!!

Way to go boys. So damn proud of you.

You can tell Simon always gets serious when people sing.

I would love to hear them sing Bohemian Rhapsody

These guys are so talented

The fact that there’s not a singular person they use as the high voice guy is amazing. They all do big notes.

It's cool that they're bringing Broadway Musical atmosphere to America's Got Talent stage 👍

This gave me 10 more years of life.

That Elphaba “oh” at the end was a solid choice 👌

If the crowd could shut up for 1 second, y'all could hear how AMAZING these guys were!!!!

You could tell the judges weren't expecting much until they hit that first note.

Honestly if they had a sad story, they would’ve gotten the gold

Simon's 'tell' that says that he absolutely loves it is when he's just staring at them wide eyed and reaction-less.

Its like listening to a recording version. That show how good they are...

Dang they just casually take that high E straight away in the beginning! You can tell theyve been singing and harmonizing aucustically in "a staurway", they sound so good together!

Sometimes I don’t like the way the judges judge them before they even start the performance, like the facial expressions when they first start talking They were awesome though!

Can we talk about how they mashed up Idina Menzel's Elsa with Idina Menzel's Elphaba? Amazing!!

Been fans of these guys on YT for a while now. Always surprised they hadn't gone more viral. So happy for them to have gotten this platform to show how insanely talented they are.

So Disney Princes is a thing now? They are the perfect fit for the theme song!

I have autism and ever since I heard this song in Frozen 2 it has been my "comfort song." I'm crying so much right now because this made me so happy. I love it

It’s embarrassing how many times I’ve watched this.

Simon was looking and stairing deep at them with his mind busy on “what if i work on them to build an astonishing celebrities “

Brandon Urie : I’m the only male who can hit that note These guys : Hold my sweater

Their voices are so well blended! That's insane! And that smile from Brendon right after their song, melted my soft heart!!! LIKE WTHHHHH!!! ❤️❤️❤️

This was sooo much fun🥰, thanks so much for having us AGT!!

They sound like there’s a 100 people singing!! Awesome

Let's be honest that this group is the most unique voice that we ever heard among the other singer in this season.

Knowing that this is live and no autotune with that pitch perfect performance. W.O.W !

now this is what you call a golden buzzer performance

Howie: I don’t like this type of music Also Howie: says yes

I love Terry's expressions when he likes something

They surprised the heck out of me!! Those voices and man the harmony. They are hitting some Mariah Carey man notes!!😊👍❤

T3 is awesome!!! Their pitch is perfect, their harmonies on point! I hope they go far in this competition.

And this is the first time they performed in front of a lot of people. GOOSEBUMPS!!!

Their harmony is everything!!! Wow!

The Wicked Defying Gravity riff at the end. Hell yeah.

Elsa must be so proud at this moment!

That was AWESOME! Remember man looks at the outside apearence. Its always those who seem to be nobodies-underdogs that become the greats!! These are the people who have the largest hearts, the most amazing smiles,crazy passions,and the biggest ideas in the world! They are the History makers! They are the World changers!!

As a first soprano who has had the honor of singing on the altar of St Patrick's Cathedral in New York City, I can honestly say these guys are amazing. Their harmonies are spot-on. Probably three of the best Tenors I have ever heard, and I have worked with a lot of tenors. Also speaking as a drummer and fellow vocalist their composure with this having been the first time they sang in front of a large audience on a large stage was amazing. I just don't have enough good words for these guys. I wish them all the best.

3 people but it felt like the whole world singing in harmony The power in their voices...God!!

I actually got chills hearing this. That NEVER happens to me when hearing someone sing

I've been doing acapella and choir/vocal music for 13+ years. The sheer amount of talent these 3 guys have alone is incredible!!

I'm prepared to be surprised

Who else thought Simon didn't like it...de way his expression.....n is surprised when he stood up?? 😂😂.

I was literally crying the entire performance! I am in awe of their greatness! ❤

Bruh! Those vocals and harmony... Take my effing money 😭

You would think that after all these years, the judges would learn to stop pre-judging or stop judging a book by its cover before hearing them sing.

Simon’s expression in that first long shot after they’ve started singing, where the table of them is visible in the background, speaks volumes about how good they are.

Disney, Pixar, SOMEONE needs to hire these guys to do music for their next animated film

Those high notes were incredible, and the harmonies... wow!

These guys sound so flippin' good together. Power. Not any more complicated than that.

So many talented in this season, wow!

Looking at Simon's reaction, i thought he is definitely going to say no 😂

This didn’t even do them justice. When they sing acapella you can really hear just how juicy those harmonies are.

Even if I ingest Helium gas, I wouldn't be able to sing like them .

This is what Disney musicals sound like!

Let's admit it, AGT 2021 talents are very spectacular and breathtaking. This season is superb!

Funny how some comments are like, "...I hope they stop pre-judging!" Guys, they're called JUDGES and it's their job! They can judge based on appearance, backstory, etc. The whole point is that their decision should be based on the talent AFTER the performance!!!!

A song so difficult that should be penalized to be sang live, and they just crushed it! 👏

This was like the Susan Boyle moment. They smirked, and looked at each other almost rolling their eyes, then she opened her mouth. These guys sound incredible together.

that high pitch gave me goosebumbs

They definitely deserve to win. They are really talented and upbeat

This is the best. I immediately got goosebumps. Frozen is my favourite movie. Seeing these guys perform.... Made me so much happy. God bless you guys. Amazing performance

Dude had a rockos modern life shirt on ,crazy how talented this dudes are

Finally an audition even bats can enjoy x)

They're too good, goosebumps everywhere! Woohoo. Perfect harmony and unison.

Wow! .. so Amazing... they should get themselves on AGT 💕 🎶 💐 👍

Honestly SO PROUD of these guys - from seeing their original KZbin cover of this to now AGT...!!!! God bless these guys, what flipping talents 😆

Now THAT is how you wipe the smugness off those judges faces!! Outstanding!

Wow, unbelievable voices just magnets & perfected a sound.

They could really voice over a Disney movie

I get chills every single time I watch this ... and I come back it to all the time lol

These guys are absolutely AMAZING!! Their harmonies are on point!!!

I wish the crowd wasn’t screaming the ENTIRE time.

Wow… that was something special… and that “Defying Gravity”; a brilliant touch

Doesn't get any better than this! These guys are perfect! Golden Buzzer from me!

Not a frozen fan, and the songs are over-sung, but I was grinning like a fool the entire time. These guys are AWESOME, and this performance was super fun!

Did anyone notice how that last run that the guy on the left was the last vocal run of DEFYING GRAVITY. Dude didn't just pick this song cause it's popular they understand that idina is the goat and I think he through in that final run as a tribute

I've been fans since they had just started on tiktok, so heckin proud

INSANNNEEEE! i've watched this video countless times and it hasn't failed to give me chills ONCE. this performance takes my breath away. if i were a judge, they'd have my golden buzzer FOR. SURE.💛

Absolutely beautiful trio,that sounds are AMAZING, can I press the golden buzzer for them 👏 👏

This gives me chills…. It hits my gizzard differently….

This is so cool, I love Idina & Brendon version but this version is so unique. they sang it so beautifully 👏 👏

I can't help watching this repeatedly. They just make me so happy watching them sign such beautiful harmonies.

The Judges Didn’t really expect This just by The way they were looking At them first. I Got goosebumps All Over🥵🔥🔥♥️ They’re Really good.😊

How can you not love these guys voice!!! Beautiful arrangement!!! ❤️

Simply unexpected.really goooood...wow wow wow for T3..

I see Simon's eyes rolling- going ka-ching! ka-ching! as he calculates future sales/profits!!!

I’ve been watching these guys’ covers for a minute! They are vocal monsters and I’m so excited they came on the show. They could go so far!!! My musical theater nerdom is showing so much😂😅. Also, green toboggan is so gorgeous😅

Yo to point out Howie hated this song when another girl sang it remember that he said he hated Broadway music

That’s the performance that made baritones cry

That defying gravity moment gave me goosebumps!!!!

I could see any one of these guys getting to Broadway! Amazing. Loved the nod to Wicked at the end!!

2:20 Idina must’ve been very proud. Impressive vocals!

I FEEL SO HAPPY, IVE BEEN WATCHING THEM THIS PAST YEAR YES THEY NEED TO WIN

Those guys shouldve gotten the golden buzzer right off the bat...they are absolutely perfect

Golden buzzer worthy performance!
