Last year the "Glad You Came" singers announced that they had "collectively decided to take time for personal endeavors," which for Nathan, meant a solo career -- something he decided to pursue as soon as the band concluded their Word of Mouth tour.
"It was when we got back from the last day of the tour," Nathan told MTV News of when he decided he was going to go solo. "And when I landed back home I kind of just sat there and was like, 'What am I going to do now?' I'm a bit odd at this and I was like, 'Look, I'm 21 years old, I'm far to young to stop doing what I love.'"
Nathan then got back in the studio, teamed up with Babyface and Diane Warren, and began working on the next phase of his music, which he describes as "soulful pop."
"I got back in the studio and started writing random stuff and then I wrote 'More Than You'll Ever Know,'" he said. "And that was when I was like 'got it.'"
Nathan is gearing up to release his debut album, which will feature "More Than You'll Ever Know" and his upcoming first single "Kiss Me Quick," and he's got nothing but support from his former bandmates Siva, Jay, Tom and Max.
"They've been great; they've been really good. I've spoken to a couple of them [and] they've been wicked and everyone is really focused on their own thing and really working hard," he said. "They haven't heard the music yet because everyone has just been so busy, but they've been really good."
