Black Tide won the best international newcomer award
Teenage band Black Tide have picked up their first ever award from music magazine Kerrang!
The rock band, who hail from Miami, were the youngest winners on the night which saw Rage Against The Machine, Slipknot and Metallica all honoured.
Singer Gabriel Garcia, who formed the band in 2004, is still just 15 years old with the oldest, drummer Steven Spence, still only 20.
The band released their debut record Light From Above earlier this year and their latest single Shout is playlisted on Radio 1.
Bass player Zakk Sandler admitted the band didn't grow up with Kerrang!, which is not sold in the States, but insisted they were delighted simply with a nomination.
He said: "It's like one of those things you read about online. You hear about them and to be involved at all is just such an honour.
Spence added: "We can just go home and be like, 'Wow, look what we've done.'"
Black Tide were seated behind Metallica at the ceremony, which could have been embarrassing as one of their members was wearing a Master Of Puppets T-shirt.
But Spence said: "Lars Ulrich from Metallica was wearing one of their own T-shirts as well! Maybe I should have worn a Black Tide shirt."
The band has already toured the UK as part of Ozzfest and are going back to the US to support Bullet For My Valentine - who picked up best British band at the awards.
They plan to come back and play more dates in the UK towards the end of the year.
Slaves to Gravity
London-based metal band Slaves to Gravity picked up the award for British newcomers.
They were formed two years ago from the ashes of a band called The *Ga*Ga*s and were joined by new lead guitarist Mark Verney.
Singer Tommy Gleeson said: "Our guitarist quit and we still felt like we had a lot more left in us and we weren't ready to give up.
Best British newcomer went to London band Slaves to Gravity
"Mark was the first guy we met and right away we started writing as much music as we could and it naturally took on a sound of its own."
Their self produced debut album, Scatter The Crow, was released in March this year.
Kerrang! described it as "brilliantly channelling the down-tuned, melodic grunge stylings of Alice In Chains, Stone Temple Pilots and Soundgarden".
Drummer Jason Thomopoulos told Newsbeat: "It's really flattering that such a big magazine has picked up on us and is supporting us."
Slaves To Gravity say they're about to start writing the second album and are heading back on the road for some more live shows.
Despite their success at last night's awards, the band say they're not too concerned with getting a covershoot with the magazine.
Gleeson said: "Nah, we can do it with Photoshop when we're bored on the tour bus."
