DJ Marshmello & Bastille 

Marshmello (real name Christopher Comstock) is an American electronic music producer and DJ. Bastille are an English indie-pop group. They have collaborated on the song ‘Happier’ together and again have blended their different music styles to complement each other.  

Dan Smith, lead singer said, 'We had a really interesting time getting to work on it with Marshmello who managed to find some euphoria in a pretty melancholy, direct song. It's always good to step into somebody else's world for a minute and we're excited to be a part of it.’
