Metal and Blues?

[Genuine17]

i would also say black sabbath i dont know if any other people can realize this but toni iommi's guitar riffs and solos are all blues based solos and definitly said by The Colonel said Led Zeppelin is almost exactly what you are looking for.. but with all rock & roll (metal included) it was completely formed from Blues.. so every song out their has deep roots to blues so your not particular going to find a band that is exactly metal/blues but more or less a few bands with a few songs like that....

I had been trying to remember the name of a Blues Artist for the longest time, his music was always real nice to jsut chill to..., and his name was always on the tip of my brain but never managed to squeeze his name out of my memory, but after reading this thread I had a surge of long term memory yay! BLIND WILLIE McTELL!!
