Kids!!! If you can grow a chin strap beard, dye your hair bright yellow, wear a baseball cap backwards unironically, and learn to play nothing but finger cords in drop D, then you too can be a nu metal superstar!!!!!!
But seriously the genre is awful, and filled to a great degree with misogynistic, dude-bro frat boy dumbfuckery. And the only band to come out of it that will have any lasting appeal to both metal historians and music fans in general is probably the Deftones.
