Killswitch Engage played the Reading and Leeds Festivals in August 2006, having already played Australian dates without Dutkiewicz, who was suffering from back problems and needed corrective surgery. On May 23, 2006, the song "This Fire Burns" was released on the "WWE Wreckless Intent" album. The track was intended to be the new theme song for WWE wrestler Randy Orton; however, it was scrapped and later became the theme song for the WWE Judgment Day 2006 pay-per-view. "This Fire Burns" was used as the entrance theme for WWE wrestler CM Punk (along with his stables the Straight Edge Society and The New Nexus) from 2006 until 2011 and was later re-released as "This Fire" on the "As Daylight Dies" Special Edition.
