There's the long-running argument that punk rock begat metal music and that's an argument mostly posited by knuckleheaded punks. The roots of metal can be traced back to groups like Blue Cheer the same way punk rock can be traced back to Question Mark & the Mysterians. In the end, it's a non-argument. It's more of a who gives a fuck argument. It's a total waste of time save for getting deep in suds and almost coming to fisticuffs with a friend.
That aside, both genres of music have pioneers, innovators, creators and a large bucket full of shitty squads. It's as lopsided as this year's Champions League. The punk and metal genres come up today in the first of a series of fluffy blogs examining the crossover success of bands in one covering songs of another. The link between metal and punk is undeniable, regardless of who is whose daddy.
