Tamdan McCrory, who came out at UFC 91 to Dimmu Borgir, had his request to walkout to Dethlok’s “Thunderhorse” (from the show Metalocalypse) vetoed by Dana White. McCrory felt music to be so tied to his identity to the viewers he absolutely needed (Tamdan grabs the mic and its the first thing he says in his post-fight speech) to alert fight fans that his walkout music was not his choice.
