So wait, does Kellin Quinn perform different Titan Boss Songs for each performance? Regardless, it's nice to know that he's performing at the symphony!

The fact that all it took was the first guitar riff for people to realize it was Undefeatable and everyone starts losing their minds. Wish i coulda been there.

kellin should sing this with his band, sleeping with sirens.

There’s not many singers who sound alike if not better than the original song. It’s crazy that Kellin sounds so much better here than the song itself he absolutely knocked it out of the park.

The way everyone sang along tickles my heart in a very good way. This song fucking rocks.

I hope someday Kellin Quinn and Tyler Smith will appear at the next "sonic concert" so that they can sing Find Your Flame. That would be awesome. (P. S. : sorry if my English is kinda "rusty", I'm Peruvian)

While they didn't perform this at the London one (doing Break through it all instead) I'm glad that this song got performed at one of these concerts.

Watching this gave me chills and I love it

being able to sing to this live was an otherworldly experience

Could someone please upload a version of the full Undefeatable music video that plays in the background? On the official channel, it just plays the first part of the song and not fully

I hope the official Sonic the Hedgehog channel releases this full version of the animated lyrics after some time, they look great

BRO, THIS

You know what, he deserves the recognition...

Master piece.

This has made my day after hearing kellin on sonic frontiers I became obsessed with his music as it's been amazing from every moment I've heard and to hear him finally perform this live is amazing.

I never knew that a symphony can be in a heavy metal band like this.

He sounds so good live no one can deny that 🙌

And they said Genshin Impact was the winner, those Game Awards fuckers didn't know that Sonic Frontiers won literally harder, in terms of power, combat, story (DLC included) and most of all,

It's so wild to me that they got Kellin to do sonic music. I was OBSESSED with Sleeping With Sirens in College and HERE WE ARE AAAAAAH

I would love to see Kellin Quinn live! He's one of my favorite artists
