Recorded after frontman Deryck Whibley almost died from alcohol-related liver and kidney failure, Sum 41's sixth album is the heaviest work the Canadian pop-punk group ever released—on multiple levels. The lovely piano ballad "War" finds him assessing the damage he's done to himself; returning guitarist Dave Baksh’s Iron Maiden-inspired, intricately tapped guitar solos blend smoothly back into the group's pop-punk sound, especially on "Fake My Own Death" and "Goddamn I'm Dead Again," helping the album reach an overall triumphant mood.
