Chicago based OK Go are known for many things. They recorded an EP to raise money for New Orleans musicians displaced by Hurricane Katrina. They made a cameo appearance in the 2009 comedy, "I Love You, Man." They've toured with Panic at the Disco, Snow Patrol and Motion City Soundtrack. And yes, they were the guys who became international sensations after performing a perfectly choreographed dance on treadmills in their 2006 music video, "Here It Goes Again." Now, OK Go is back in the spotlight, recently releasing their third full-length studio album, "Of the Blue Colour of the Sky." Band frontman Damian Kulash describes the new record as "a more contemplative record, but also much more anthemic, much dancier. And it’s a way more emotional record than anything we’ve done. So it’s both sadder and happier in its way.".
