When I was 16, I saw Stevie Nicks perform live at a place called Red Rocks, a gorgeous venue carved out of a natural amphitheater in the Colorado mountains. It wasn’t my first concert. It wasn’t even my first Red Rocks concert, though I think it was the first concert where I was at all close to the stage (I was probably in the 5th row or so.) It was, however, the first show that affected me deeply. In fact, I’d even say it changed my life.
