10 Legendary Rock Bands That Got Darker Over Time
3. Sum 41
For every band that is on this list, Sum 41 going heavy feels like it makes the least sense out of all of them. From the minute that you heard a song like In Too Deep, this was supposed to be the band that would soundtrack pool parties for the rest of their lives and become a staple of the suburbia circuit. All Killer No Filler may have been a good starting point, but they started to listen a little closer to their influences as the years went on.
Just like the lyrics in Fat Lip would suggest, Maiden and Priest had always been a major part of the group's upbringing, and Chuck was the turning point where things started to change. While the rest of the pop punk bands were still milking the cheesy side of the rock scene, Sum managed to combine metal and punk into a weird concoction and pulled it off fairly well, including punk takes on Metallica's sound like the Bitter End.
In the aftermath of that album, they seemed to be getting heavier on each passing album, like the more pointed subject matter on the album Underclass Hero or turning their lineup into a three guitar attack on albums like 13 Voices. They may have started out in pop punk, but at this point, Sum 41 are basically a full on punk band. Maybe that was just their calling, or maybe that's just what happens when the scene starts to grow up.
