This arcane and eerie piece is taken from Zeps 1973 LP, Houses Of The Holy and is basically a vehicle for John Paul Jones to go all moody and dark with his watery piano. The opening bars trickle in slowly before a crack of lightning from Pages guitar introduce a deep wah-wah riff that will absolutely haunt your dreams. It tos and fros with muggy vocals from Plant whispering lyrics about the dogs of doom and winds of Thor. The opaque production of the track would directly influence the grunge scene of the early 90s.
