It’s official. Ozzfest and Knotfest will be joining forces in San Bernardino, California on September 24-25. So far as live metal shows go, this will be one of the biggest the United States has seen in awhile. A collision of titans, if you will. You can take a look over the combined line ups above and get more information about the shows through the links found at the bottom of this page. And, of course, we included tracks from the two headliners just as well. It’s hard to put into words how great this weekend in San Bernardino will be. Definitely go if you’re able.
