Looking upon the stage from the top of Red Rocks Amphitheater, I saw a rock band decked to the nines in flared pants, tie-dye and bandanas. I heard what I presumed to be an adult opening act covering classic rock favorites — it wasn’t until I reached the front row that I realized the person clad in an elaborate glam-rock outfit was Ethan, a tyke from Boulder, who tore up the mic with a swagger expected of someone who has reached double digits.
