How popular is Red Rocks Amphitheatre with musicians? Let’s put it this way, The Beatles played there. But that was a long time ago, right? Well, the big-name bands never stopped. Modern acts like Nine Inch Nails, Foo Fighters and Jack Johnson, among dozens of other notables, played there in 2008. What’s even more impressive than the set lists is the scenery. Red Rocks is a naturally formed amphitheater, where seats were carved right out of the mountain, and where ginormous rocks (red in color, of course) corral the stage in a perfect sound-amplifying amphitheater.
