19:11 - moonflash I concur, this isn't the kind of "evolution" which was meant to get rid of the precursor, it's just another way of expressing the influence blues and rock had on metal. Similar to the way death "evolved" from thrash.
19:02 - Fritillaria oh no not again, metal didn't evolve from blues or rock, they just influenced it
19:01 - moonflash Well I'd consider them a very early form of heavy metal. Metal evolved from blues based hard rock and Led Zeppelin were one of the first bands to endeavour in heavier, more progressive areas which eventually became "heavy metal".
18:53 - Fritillaria Led Zeppelin ? was mostly hard rock, not metal I think
