rudimentary peni is some good ol'school punk i dont think anyone mentioned. u can break punk down soo many ways, alot of true punk bands that werent named, u have the 77' era the 82' era. oi, street/chaos, then to me u have underground "pop-y" punk ie.. pretty much all the bands on epitaph, and fat wreck cords. millencollin,nofx,strungout,pennywise,deviates, stuff like that. i was real hardcore into street punk/oi in highschool, to me it doesnt get more "real" or "core" then that. most of the bands live in ny area(not all). ie.. aglobal threat, defiance, lowerclass brats, clit 45, oxymoron,devotchkas, aus rotten, self destruct, the virus bands like that.
