"Fat Lip" by Sum 41

Birthday wishes go out today to Dave Baksh, founding member and former lead guitarist of Canadian pop-punk trio Sum 41; since leaving that group in 2006, Baksh has been affiliated with the metal-reggae quintet Brown Brigade.

Fat Lip was the first single from the band's second album, 2001's All Killer No Filler, and is arguably the band's biggest single to date; Rolling Stone magazine described the sound of the song as if Sum 41 went from blink-182 to Beastie Boys to Black Sabbath, all in one song - which seems an entirely apt description of the proceedings.
