I first heard Nick Jonas where most people heard him; on the Disney Channel with his brothers. Together, they were the Jonas Brothers. My kid sister absolutely loved him, as a ton of teenage girls do.
So one Summer, I surprised her with tickets to go see him play live. When buying the tickets, I was expecting it to be a concert of the Jonas Brothers playing together, but when I got there, it was just him with a guitar, drummer, and some backup singers. I had absolutely no idea he had taken the solo career route.
The crowd was what you would expect at an attractive pop singer's concert: Absolutely packed with pre-teen and teenage girls. There were also a lot of dads there which made the experience that much more enjoyable. Seeing their expressions when the girls would scream at the top of their lungs was hilarious.
Anyway, Nick Jonas is an amazing singer and guitar player, he was very energetic on stage, jumping up and down, touching the girls' hands (which made their night). I was extremely impressed. He had a lot of very catchy songs that I never heard as I was only familiar with his songs when he was in the band with his brothers. We both had a very good time, and so did everyone there. Its cool to see Nick make the transition from successful member of a boy band to succeeding at his own solo career.
