Some fans may not know that in 2001, Fuzz Kmak broke his leg on a fire escape. At that time, Disturbed was touring, so they found a bass player to fill in. That bass player is Marty O'Brien. Not many pictures exist with Disturbed having Marty O'Brien as the bassist, but this is one better, a video with Marty as the bassist. This is the only pro shot video I know of on the Internet that has Marty as the bassist.
