Finally, I've been waiting for this one since the first time I heard it. 'Calling' is a wonderful, epic track made by Swedish producers Sebastian Ingrosso and Alesso and released on Refune Records. This is, according to Beatport.com, the instrumental mix, so maybe we will see a vocal mix in the future, that would be amazing. Don't hesitate and check it out!
