Yes, you read that right. Hanson has officially been a band for 21 years. Do you feel old yet? Because I do. To celebrate their birthday the band played a special anniversary show at Irving Plaza last night (June 17) and released their album Anthem today (June 18). If you missed all the action last night, the band will be playing their CD release show at Irving tonight, followed by a full US tour in the fall. Check out some photos from the concert!
