In contrast to British punk rock, American punk rock was rougher and less rooted in classic rock 'n' roll. US punk bands relied on extreme reductionism and speed, setting the direction for what would later become hardcore or hardcore punk. This mixtape captures the time when the division between punk and hardcore was not yet apparent. The spirit of the sound is much more rebellious and chaotic than later in hardcore, the destruction of listening habits, the brutality and speed more extreme than in what would later be sorted into the other drawer, namely punk. It's this hybrid moment that made the whole thing so exciting.
