No discussion of Colorado music is complete without Red Rocks. Hands down the best live music venue in the world, attending a concert at Red Rocks is as much about the experience as the artist. Get there early to tailgate in the parking lot, walk up the intense stair climb to the theatre (being a beer for the walk, there are recycling stations on the way), and watch the biggest names in music with incredible views of the mountains, the red rocks, and the city of Denver.
