This is absolutely incredible. I've gotten much more into metal this year; unfortunately this only further enables that!

One disagreement: punk rock island should be a lot bigger in my opinion!

Garage and heavy metal definitely inspired the OG British punk rock scene, but they also inspired NY Dolls and Ramones (who formed specifically in response to the rising popularity of heavy metal, if memory serves), two massively influential bands that progenated several subgenres (pop-punk, which created Descendents, Green Day, Blink 182, etc; Ramones-core; melodic punk). DOA and Black Flag, both of whom are mentioned on the map, also helped inspire the whole Nardcore/West Coast thrash scene (RKL, DI, etc), which was happening, almost rebelliously, at the same time in the East Coast (Gang Green/Jerry's Kids, Proletariat, basically everyone on the "This is Boston, Not LA" album, which is fantastic and still holds up IMO).

I'm going to stop there because if I go any deeper, I'll have to start talking about emo, and that will for sure crash your map.

Anyway, metal is helping cleanse that part of my life; going to spend a lot of time going through the playlists in this map. :)

Thank you for making it!

I interpret each of those outlying islands as representing an external influence to metal that is not elaborated further. Of course that island needs to be bigger, but so should the hard rock and psychedelic rock islands -- and they should extend into the 70s and 80s as well.

But this is a map of metal, not a map of music. If one were to draw a map of punk, metal would also just feature as a few small islands I gather, along with islands not mentioned here such as surf, reggae and hip hop.

Fair enough! I guess you'd just recreate the universe if each genre were expanded upon further.
