when i first posted i tried emphasis that they are not easily placed into any catagory. ands some people say hard rock, but i think they are just so much heavier than that. Also i when we think about metal we think about metal bands like Pantera, Metallica, or Slipknot, i know Zeppelin doesn't sound like they do and im glad, but to me they were one of the first metal bands, i think that the metal sound has evolved so much people hesitat to call them metal, but its the same with classical music, earlier classical music is just as different from later classical music as Zeppelin is to modern met
