Hanson may still be best known for their still sublime pop smash "Mmmbop," but the brothers Isaac, Zac and Taylor have parlayed that '90s anthem into an impressive career that spans just over 20 years. The band recently released their ninth studio LP, Anthem, and will be touring North America through November, after which they'll head to Europe for a few more dates. All that traveling is nothing new for Hanson, who still relish each performance and always make time for their fans before and after the show. Rolling Stone caught up with Hanson before their recent gig at Boston's House of Blues and spent the day walking (sometimes barefoot) around and rocking out with the band and their fans.  —Jon Blistein
