Led Zeppelin, a band for the ages, creating a sophisticated hybrid of blues, folk & rock music. A band with no limits who eschewed the singles oriented rock formula & pursued a strategy built around albums. They were capable of intense visceral power as well as supreme finesse, as exemplified by the bludgeoning strength of Ramble On to the exquisitely folky That’s the Way.
Sorry for editing The Song Remains the Same, but I believe it was originally intended as an instrumental & it should of stayed that, Plant’s early vocal histrionics really destroys the momentum of the song.
