In the July 12 episode of " America's Got Talent," viewers met Acapop Kids the teen Cappella group made up of 12- to 17-year-old students.

The group dedicated their show to Nolan Gibbons, one of their members who passed away at the age of 15 due to Sudden Unexpected death within Childhood (SUDC).

In the days before his passing, he wrote the hit song "My Turn" in which kids were able to sing on the platform for the purpose 

of "honor him" before "AGT" the judges Simon Cowell, Heidi Klum, and Sofia Vergara ( Howie Mandel was sick).

The band members talk about that they're from all over the U.S. and that they've "been together for four years at this point."

According to them, the self-proclaimed "best friends" have a desire to "go on tour" as their ultimate goal and "inspire youngsters

everywhere to be whatever they like regardless of their appearance"Nothing will keep anyone from doing it."

We're simply here to share his message and become an instrument for his message." Simon apologizes for the loss of his 

a friend and encourages the singers to "take the time to beat" and get ready for the audition, which could transform their lives.

The nine teens line up and begin their inspiring Cappella rendition of the song "My Turn" with solo singing, humming, and beatboxing.
