It's 'Intro' by M83. Great song/band (AFAIK, who know what any musicians ideology is these days). The album is a banger.

We didn't need a story, we didn't need a real world We just had to keep walking And we became the stories, we became the places We were the lights, the deserts, the faraway worlds We were you before you even existed Carry on, carry on, carry on And after us the flood Carry on, carry on, carry on Our silver horn it leads the way Banners of gold shine In the cold, in the cold, in the cold Footprints of snow, blind from the road Hail! We carry on, carry on Follow us, we are one The battle's fought, the deed is done Our silver hum runs deep and strong Hand to the heart, lips to the horn We can save, we can be reborn Head on my breast, I'll keep you warm Hail!
