They have been scouted by Metallica for a major festival, are set to open for Queens of the Stone Age and could make up to US$1.8 million (NZ$2.04 million) in a new record deal with Sony.
But for the three eighth-graders who make up Brooklyn metal trio Unlocking The Truth, it's a case of learning before earning.
"School work comes first," said Annette Jackson, band co-manager and mother of guitarist Malcolm Brickhouse. "If their school work is not done, they don't play," she told the New York Daily News.
A video of the three performing their song Monster went viral, with more than 1.5 million views, attracting the attention of a Sony executive. Last year Brickhouse, 13, bassist Alec Atkins, 13, and drummer Jarad Dawkins, 12, took to busking on a street corner in New York's Times Square.
The Manhattan Supreme Court last week cleared a deal between Sony and the children, which could see them earn a seven-figure sum from five albums.
"I'm so excited! We've made it!" Dawkins told the New York Post.
The contract could prove a bargain for the label if Unlocking the Truth realises its ambition to become "one of the world's best metal bands".
But the full deal hinges on their first album selling more than 250,000 copies, a big ask for any industry newcomer.
Band co-manager Alan Sacks told Rolling Stone "a major guy in the genre" was on board to produce the debut.
"The boys have their music written, so we're in good shape," he said. "We're just finalising those situations right now. Metallica also reached out to us to get us booked on the Heavy Montreal festival [in August]."
Unlocking the Truth have already opened for legends such as Guns N' Roses and Motorhead.
They also have a book due to be published by Penguin before Christmas and a documentary in the works.
