And I'm still waiting for you to post some examples of other hardcore bands that sound like GG Allin. Sit and wonder about that for a while, kid.
Rawness, loudness, extreme topics and vocal style aren't qualifiers for being hardcore punk, riff types are very important as is the drumming. GG Allin just took punk rock riffs and recorded them really badly.
This is hardcore punk.
Show me a GG Allin song that sounds like this.
