The Hanson brothers have come a long way since their ‘MmmBop’ days, with nine studio albums under their belt and well over 15 years of creating music together. The band rocked New York City’s Irving Plaza last night for the release of their latest disc ‘Anthem,’ which boasts the catchy single 'Get the Girl Back' and the funk sounding 'I've Got Soul.'
