70’s Heavy & Proto Heavy Metal Compilation.

Tracklist in the comments⤵️ Lista de temas en los comentarios⤵️ Welcome, this is just a small compilation of some bands that powered Heavy Metal in the 70’s before the British in 1979 renamed it as a new wave of heavy metal, however, any psychedelic hard rock band of the 70s is cataloged As a proto heavy metal, what I did was just choose the most relevant and the most objective, unfortunately, my planned catalog was about 125 bands so I had to get rid of many of them, maybe in some future I can launch the second edition of this collection.
