The term "Dad Rock" is something that gets thrown around a lot these days, and no bands breathe the rock of our fathers like Styx and Yes. Last night, both of these classic bands made a stop at Red Rocks Amphitheatre. Our resident photographer, Brandon Marshall, was on hand to capture the magic of the evening and brought us back a bunch of photos, which, of course, we've posted below for your viewing pleasure. Scroll through to the bottom of the post to see two fan-shot videos, as well.
