The US band wrote and recorded a song with the Belgian seven-piece after they won the Play and Stay at Aloft competition.
Asked how the competition had gone, Chris Cain told Digital Spy: "It went exactly as we predicted. Do you remember the eerie details we gave you? They all came true - they all came to pass!
"They are one fresh-faced little gang. We're excited to see if they can even lift their instruments. "
Keith Murray added: "They're very young. Seven people, one of them female, six of them... undetermined! No, six male, they're from Antwerp in Belgium.
"I've been telling other people that this is their first time out of Antwerp... I think it's their first time out of continental Europe.
"There are two horns and when we first watched their concert video, I said - inaccurately - that they were the Pavement of Belgium. That's the quote from me."
Cain said: "Disregarding the actual pavements in Belgium."
On what advice they imparted during the process, Murray said:"The funny part is that they ended up mentoring us.
"They know way more of this stuff than we do. It turns out I've been holding my guitar upside down all this time."
Cain joked: "I think it's just a symptom of how sick the industry is that a successful band like us managed to get past all the gatekeepers without even knowing how to hold a guitar.
"We told them to ignore the producer. Unfortunately he was in the room at the time and I think our relations soured from then on."
Murray said: "Luckily that was about six hours in, so I think they got most of the important stuff done."
Asked about their own upcoming studio album, Cain said: "It's mostly recorded, it's not done yet, we're going to finish it up at the end of this month... and I think we're going to call it... Sky Castles."
