To us, and we're sure to many of our readers, rock stars are the true superheroes. And now that classic rock has been around for over five decades, some of the genre's biggest names are revealing themselves to be real-life Iron Men.

Last summer, we asked you to cast classic rock's version of the Avengers superhero team. This year, to celebrate the release of the summer blockbuster 'Iron Man 3,' we've teamed up once again with our favorite musical avengers, Loudwire and Diffuser.fm, to look at the musicians who have overcome adversity and turmoil to build some of the longest, most successful careers in rock history.

So grab your popcorn, strap on your protective metal armor and get ready to meet the Iron Men of Rock.
