Amphetamine Reptile stuff? If you're not exactly sure what I'm saying, the easiest way to put it is pretty much anyone influenced by the likes of Jesus Lizard, Helmet, Unsane, etc.

If you still have no idea what I'm talking about and are kinda curious, I mean bands such as:

Gunna Vahm - https://www.youtube.com/watch?v=Ket5-VHQc1s&index=2&list=PLDAyGxoUAFVUf8Jb8QPVpc8NbJ6aC72ZA

Breather Resist - https://www.youtube.com/watch?v=rpzwAqjw8cU

Fight Amp - https://www.youtube.com/watch?v=QJwceRA49W0

I can't be the only one here...

If I'm not, let's talk about how ridiculously awesome this sect of hardcore was / is (moreso the former), and how hideously underrated the genre always has been.
