Sum 41 - ChuckIn May, Canadian punkers Sum 41 faced rebel gunfire in the Democratic Republic of the Congo while filming a documentary about war. The group’s third album, named for the United Nations worker, Chuck Pelletier, who saved their lives in Africa, is a naturally more grown-up affair, full of thoughtful ballads and melodic rage. Call it protest metal or political thrash, but songs like the Oasis-like “Some Say” and “We’re All to Blame,” with the clever lyric “supersize our tragedy,” are catchy, topical and altogether admirable.
