actually, wasnt punk in its hey day in 75/76, as was Nugent and Kansas, by mid/late 70's we had Van Halen, UFO, Scorpions, AC/DC to name a few. Punk was irrelevent though a handfull try to proclaim it was. The new wave of heavy metal bands were inspired by the old "heavy metal bands", progressive rock or hardrock bands that fell to commercialism or just ran their course. Punk was more responsible for "new wave" if anything. Its said the thrash bands had some punk influence but thats not the only kind of metal and not really connected to the NWOBHM. Myself I dont hear a shred of "punk" in Iron Maiden, Sabbath, Dio, Savatage, Fates Warning, Helloween or even Metallica for that matter. (I know only Maiden is considered NW metal) Punk was both a rebellion against pop music, disco and complexity, for the life of me I dont see how that correlates with metal due to the complexity and effort put into the music by metal bands. Punk was anti effort.... anti everything.
