Last night (June 6) at the Sounds Like Paper Magazine Party at the House of Vans in Brooklyn, Joe Jonas performed four songs from his upcoming solo debut -- his first musical foray since older brother Kevin got married and the Jonas Brothers went on an unofficial hiatus more than a year ago.

Anyone who still thinks of Jonas as the little boy performing with his brothers alongside Demi Lovato in "Camp Rock" is going to be shocked when his album "Fast Life" drops in September. The now 21-year-old former Disney superstar is going solo and growing up, taking his boy band moves to a new, manly level.

Opening with much-hyped but still unreleased "Love Slayer" and closing with his Chris Brown-penned single "See No More," Jonas performed a short set of pop tunes that had the crowd screaming and dancing along, thanks to their obvious hip-hop and club music influences.

Jonas performed choreographed dance moves alongside two female and two male back-up dancers, as if he had been plucked out of a '90s boy band music video. And that seems to be what Jonas is going for, following in the footsteps of 'N SYNC frontman Justin Timberlake as he makes a solo career post-boy band. Jonas is one of the Paper Magazine summer cover stars, and in his interview with the mag, he discussed Timberlake, calling the elder pop star an inspiration.

Two years ago, Jonas's younger brother Nick started his own solo project, Nick Jonas & the Administration, and now it's Joe's turn. Nick sat down last month for a live Q&A with Billboard.com and talked about Joe's album.

"I think that he's had a lot for a long tome that he's wanted to say -- some things that he talks about on this record," said Nick, explaining that he wouldn't be coming out with new music until his brother had time to shine.

When the album releases this fall, Jonas will have his moment to shine, and fans who grew up with the band will be able to see the young pop star in a new, adult light. He opens up in his new tracks, singing about life in the spotlight and the ups and downs of his relationships.

After Jonas finished his set, he moved to the back of the room, energetically dancing and jumping as fellow Paper Magazine cover boy Swizz Beatz closed the show with a selection of hits and a guest appearance by New York Knicks star Carmelo Anthony.
