There were several elaborate entrances during WrestleMania. One of them involved Bray Wyatt and the Wyatt Family having a band perform their entrance. The "Live In Fear" song that Bray Wyatt uses is performed by Mark Crozer. He's a British musician that was shown talking about getting to perform at WrestleMania. Crozer said that it was completely overwhelming to be at WrestleMania. He said that muic helps to give somebody depth. Good point. Wyatt's match with Cena was shown only briefly with Cena getting the win with the Attitude Adjustment for the clean win. At another point in the documentary you could see Cena talking to Wyatt, Rowan and Harper about their match although they were merely in the background.
