As you may or may not have heard, British pop sensation Ellie Goulding performed an acoustic set on the roof of The Standard, Downtown LA the other day as part of the Vevo Go concert series. Why? Because Los Angeles is the city of angels dreams, where Anything Could Happen, and usually does, like your favorite top-forty singer suddenly appearing out of nowhere to serenade you on a rooftop. You came for a few cocktails; you ended up seeing a free concert. What the eff? This sort of thing happens all the time out there, it's crazy. Extra special behind-the-scenes footage below!
