Nick Jonas has spent over a decade in the business as a performer, but with his latest solo album, Last Year Was Complicated, the singer-songwriter is revealing a vulnerability and diving deeper into R&B in his follow-up to 2014's Nick Jonas. But Jonas' history goes deeper than being in a boy band, the Jonas Brothers, as a teenager. The eclectic star launched his career at the age of 10 with his Broadway career before transitioning to Christian pop solo star. Even during the Jonas Brothers, he spread his wings to explore his love of Springsteen and blues-rock with the Administration. All the while, the youngest JoBro shined as a songwriter, penning almost every song on his projects. Here, we take a look back at his journey as not only a star but a songwriter as well.
