Best place to see a concert easily. I have too many concerts to list here but out of all of them, only two places come to mind as the most memorable. One venue was at the Berlin Wall(when it existed), the other is Red Rocks. Both of these venues give you a view that you cannot see anywhere else. This is undoubtedly the best venue in the U.S. for live music.
