Descendents' first long player is credited with being one of the first (if not the first) melodic hardcore records. The blending of catchy melodies with speedy tempos topped with goofball lyrics about girls and conformity was a new formula in the early 1980's southern California hardcore scene, but it has gone on to become one of the most copied formulas in the genre.
The cover art was inspired by drawings that were made of (lead singer) Milo Aukerman in his childhood. A classmate would draw pictures of him depicting him as the class nerd, exaggerating his big, thick glasses and goofy hair cut. This caricature of Aukerman would be used as a template for many of the Descendents' subsequent releases, and has become one of the most immediately recognizable images in rock music.
