Man, Dan Smith from Bastille is in great shape.

Following several 'winded' remarks about our high altitude at Saturday night's show at Red Rocks Amphitheatre, the frontman announced that at every show, he attempts to make it to the back of the crowd, and this show would be no different.

Any altitude-acclimated Coloradan can tell you, it's hard enough to climb to the top of the venue's steps while holding a conversation -- and that is without thousands of cellphone-wielding fans. I'll be honest, we were a little worried.

But, Smith gave it his best shot during 'Flaws,' and though he was disappointed he did not end up making it all the way to the back, he did make it pretty far, and we were damn impressed. He's got some iron lungs.
