These four New Yorkers, currently on tour with Jamie N Commons, hit the ground running in 2009 (as Ambassadors), though they didn't really hit the world stage until last year. In 2012 & 2013, X Ambassadors had three of their songs featured in separate Need for Speed games. They also featured on Eminem's The Marshal Mathers LP2 in "Wicked Ways".
Their most recent work, and I know you've heard it, "Jungle", has flooded the mainstream lately. Featured in Hercules, WWE, Orange is the New Black, MTV's Teen Wolf, and the new Battlefield trailer, it is impossible to avoid, not that you'd want to. These guys are good at what they do, and there's no doubt that they're nowhere near done giving us music to use as background noise to explosions.
