"All Killer No Filler" was, without question, one of the most energetic and driving releases in all of 2001. A rarety in that it was way more "punk" than it was "pop," the only issue with that album, and its predecessor "Half Hour of Power," was that the sound they were going for was being attepted by hundreds of other bands at the time. In 2002, while most of the bands similar to Sum 41 were going screamo or eyeliner or whatever, they released the metal-influenced "Does This Look Infected," which started out with a HUGE bang but ended with quite a few weak songs. By 2004, when "Chuck" was released, it appeared that the band had adopted the punk-metal sound permanently, which wasn't a bad thing, since the songs "No Reason" and the vastly underrated ballad "Pieces" were among Sum 41's best tracks. Problem was, other than three somgs or so, the album didn't develop a consistent hook or vibe, and began to sound strikingly similar to Metallica's new stuff, which is not good for anyone. So a change was in order, and change they did, taking two plus years to release "Underclass Hero," not to be confused with Green Day's "Working Class Hero." What sets "Undeclass Hero" apart from the rest is the band's raw ability to write energetic, absolutely blasting melodies and short riffs. Throw in Deryk Whibley's sing/shout/rap style, and POW! you've got a punk rock record. The album gets a little political on occasion on the track "March of the Dogs" where you can hear the phrases like "The President's Dead" over and over. On the single Underclass Hero, it is just pure melodic energy, "Dookie" times ten. No band has ever cooked up this much energy on a mainstream release, as many of the tracks reverberate with a freshness that inspires those who have become so tired of whiny emo trash and the redundancy and arrogance of hip-hop. Want a good album to blast in your car this summer with the windows down, and tired of all of the bands out there who follow the scene and come up short, then purchase this album today, it may be what the doctor ordered. It is plainly evident throughout this album that Sum 41 is back, and back to making the type of records that their fans love best.
