Right up front, I'll tell you two things about this video. First of all, it's almost 15 minutes long, but don't let that deter you. This Rock and Roll mash-up is truly mesmerizing. I started watching it and, before I knew it, the video was over.

The second thing I want to tell you is that the title, "History of Rock" is a bit misleading. Yes, it all starts with Elvis, but, other than that, most of the songs and artists have nothing to do with the early days of rock. Still, contained in this video mash-up are countless songs and well over 100 different rock groups and solo stars.

Turn this one up to 11 and prepare to mesmerized for 15 minutes
