Steelheart was performing "Dancing in the Fire" from the "Tangled in Reins" album when Matijevic was involved in a serious accident. Matijevic decided to climb a lighting truss which was for some reason improperly secured so as Matijevic climbed the rig it broke free. Matijevic tried to dodge the 1000 pound piece of equipment to no avail, it hit him in the back of the head, driving him face first into the stage.
The outcome of the accident was a broken nose, cheekbone, jaw, twisted spine, and severe memory loss. That was the last time the original lineup of Steelheart would ever perform together.
