Reddit mentions of What Is Punk?

Hey Shreddit! I've been thinking about writing a children's book about metal. Similar to Eric Morse's "What Is Punk?" I've met so many cool parents who let their kids listen to metal and I thought it would be cool to respectively pay homage to the genre for kids who are just getting into metal. It would involve key influential bands, what headbanging and devil horns are, and more importantly the community of metal. If you guys have any input on what bands should be in the book or ideas of how I could begin this endeavour, please let me know. I really want to make this happen!
