Singer Nick Carter from the Backstreet Boys was in town last week for the band’s DNA World Tour concert performance at Portland’s Moda Center. And ahead of the show he took the afternoon to meet fans Aug. 22 and perform an acoustic set at Bunk Sandwiches in SE Portland. Nicole DeCosta caught up with the pop singer to discuss his solo career, how fame has changed since the band first formed in 1993, and what his fans mean to him.
