Another concert season is gearing up, and you probably already have a few Red Rocks concerts on your must-do list this summer. There's no doubt that the beautiful outdoor venue is magical, with its soaring rock formations, natural surroundings, and amazing acoustics, all under the blue Colorado sky. 

But there's more than meets the eye to Red Rocks. It comes as a hidden tunnel that holds a treasure of music history. 

We all know about the impressive Colorado Music Hall of Fame museum on the grounds, which guides fans through decades and decades of acts, tunes, and history. Just beyond the public's view is a tunnel backstage at Red Rocks, all behind a wood and iron door. It spans from under the stage to the sound engineering room, and the signatures and messages from past acts are on its walls. The signatures and scrawls are milestones in history, from acts that are making their first appearance to those that have toured worldwide and played a set or two on the Red Rocks stage. 

Signatures from sound technicians to Grammy winners like Bon Iver literally cover the walls. Santana left his mark, as did Wilco, Dierks Bentley, and so many more. 

Unfortunately, this part of the venue is off-limits to the general public, so unless you "know a guy," you will unlikely get to see this part of Red Rocks. But it's fun to know that just below the stage, a record of musical milestones is ever-growing with names from all over the industry. 

Of course, you can still check out the awesome museum at Red Rocks, which has memorabilia and photos of the acts that have passed through the venue, as well as blueprints of the venue and much more.
