Nick Jonas Says Solo Album 'Who I Am' Is 'Definitely Different'

'It's an emotional experience,' he says of his album with the Administration.

Nick Jonas and the Administration's debut album, Who I Am, is in stores Tuesday and the band's frontman and pop superstar says the LP definitely shows the teen heartthrob's growth as a musician and songwriter. He also hopes fans of the Jonas Brothers will be able to relate to the album's more mature songs.

"Although it's louder at times, it's a bit out there. And it's an emotional experience. It's some of the most challenging vocally, so I'm going to have to be wise with how I spend my free time," he told MTV News. "It was definitely different, I think -- starting to write the record I realized stylistically these songs were different than the Jonas Brothers sound."

The album, which [article id="1627922"]he describes as "a real, raw rock record,"[/article] came to fruition when he met with John Fields, who has worked with the Jonas Brothers in the past. "And I met with our producer, John Fields, and I said, 'Look, I got all these songs that I'm writing and I think it would be cool to go and make a side project,' " he explained. "It would have been difficult if I [were] trying too hard. ... These [songs] were just pouring out of me, and it wasn't like, 'I've gotta write these songs for this project' -- it just happened," he explained. "It was an easier process. It ended up being a fun, cool challenge."

With the LP's title track garnering attention, Nick guesses that he may have a next single in [article id="1629049"]"Rose Garden,"[/article] the song he debuted on Ryan Seacrest's radio show late last year. "We're not completely sure yet. We're taking it one step at a time," Jonas responded. "It's one of my favorite songs on the record, so we'll see."

Despite the solo album, [article id="1630702"]Nick promises he will be working with his brothers again soon[/article]. "We're definitely not breaking up, and we've got a lot of exciting things coming this year as the Jonas Brothers and individually," he said. "A lot of things coming up ... so that's why we think it's funny when people say we're breaking up, because we're going to be so busy."
