Red Rocks is still one of the best outdoor settings I've been to. People died at the Indiana Fairgrounds even tho they saw the monster thunderstorm coming from miles away. I've worked so many outdoor shows that should've been cancelled due to weather (rain, tornado once, blowing ice, etc.). Outdoor gigs have so many issues other than weather---primarily you never have enough power. There are no walls or ceiling, so the sound just goes. At least Red Rocks has walls, and the sloping seating makes for a better chance of hearing the band. That, and the place is beautiful!
