Montell2099 and Sachi are making history as the first New Zealand artists to get the call up to take the stage at Tomorrowland.
Sachi is duo Nick Crisp and Will Thomas, who couldn't be more excited.
After a run of shows over the past year, the pair felt lucky to get up on stage when they could.
"It hasn't been all doom and gloom. We've had sprinkles of shows and tours along the way, so there have been some saving moments," said Thomas.
But ever since the early days of the pair making music together, they always looked toward the big festivals overseas - and Tomorrowland is at the top of that list.
"It's an amazing privilege, to be honest. It's obviously our biggest achievement to date and it's at the top of the ladder," said Crisp.
"Actually getting the assets from the Tomorrowland festival with our names on it and the poster and seeing all that stuff is like wow, we're literally like a part of this now. Tomorrowland is very much the mecca of dance music, especially in Europe," said Thomas.
"I think the reality of it will very much be settling in when are getting off the plane in Belgium and going to the festival and getting up on stage there - it's going to be a surreal feeling."
Starting in 2005 with just 10,000 music fans, Tomorrowland now hosts more than 400,000 people from around the world.
Tickets can sell out in minutes and the festival has hosted the likes of Avicii, Carl Cox, David Guetta and Swedish House Mafia.
This year, it's themed 'The Reflection of Love' and more than 700 artists are set to take the stage - including our talent from Aotearoa.
Montell2099, real name Montell Pinny, has become a force within the local electronic industry over the past few years.
These days he's almost always the final act of the night at our biggest events like Hidden Valley and Bay Dreams.
He's known for creating an upbeat vibe fans stick around to the very end of the night to be a part of.
Pinny and Belgian DJ Netsky have just released their new track 'Broken'.
"I'm really excited to get that one out. It's super humbling that I get to work with an artist that I look up to," said Pinny.
Netsky will be hosting the Kiwi lads ahead of their Tomorrowland debut.
It's an achievement that signals the sky is the limit.
"It's inspiring because it's like OK sweet, we're going to play Tomorrowland, what else can we do? Where else can we take this?" said Crisp.
