Semi Final: Guy Sebastian sings his incredible single, Believer

In a heartfelt and heartbreaking performance, Guy Sebastian demonstrates his stunning range and vocal ability.

Guy is world-class. If her were American or British, he'd be a global star. Being Australian is a tough gig for musicians as it's so hard to gain global exposure and recognition. This song and performance is 10/10.

Seriously didn’t even know who this guy was until I started watching the Voice blinds online and googled him. Now I’m obsessed. He’s so damn good.

Guy also wrote a song called Perfection dedicated for his wife Jules on their wedding day.. One of the best love song ever written in my opinion.

Guy Sebastian singing "Believer" was totally awesome tonight! Well done Guy, brilliant stuff!

[blesstheuniverse]

This is his best hit and should at least make an entry to Billboard 100. I hope his team is marketing this song well!

[MaybeDavid]

This is the best vocal performance I have seen on Australian television for a long, long time. Even globally, this is top notch. Well done Guy and team!! I know who I'd be choosing as a vocal coach....

He is underrated AF😔 😪 🤧.... I feel emotional 😢, coz he has the wonderful vocal in this generation. He is just amazing 👏. Its always the talentless with auto tune that are always famous in this era. What's even more beautiful is the fact that he wrote this song for his wife, Jules.
Love from PNG 🇵🇬🇵🇬
