Christian Guardino was shaking like a leaf when he stepped on stage of AGT. Singing means a world to him and this audition was his big chance for a breakthrough. Reasonably, it took him some time to shake off his nerves, but then he belted one of the best performances ever seen on this show!
Even though he is very young, Christian went through a lot in his life. For most of it, he was completely blind, until he miraculously got back his sight. He was just a young boy when doctors diagnosed him with Leber congenital amaurosis (LCA). This rare retinal disease caused him to live in darkness, and the only thing that kept him going was his music.
Before he even started singing, Simon had a feeling Christian is going to be something special, and he was so right. It’s hard to even describe the shock on judges faces when he let the first few words. Howie was particularly moved by this amazing act and he had to hit the Golden Buzzer.
